一个拥有坚实基础的游戏，尽管仍然处于早期开发阶段，但是至少核心玩法已经完备。
问题当然有，就我目前的游玩体验，总结下来有这么几点
1.科技太少又太慢，很多相对近未来的科技（如天钩）完全缺失。聚变太慢太麻烦，而且只有氘-氦3聚变，没有标准的氘氚聚变和后期的氕氕聚变，结果就是需要聚变和氦3开采科技全部研发后才能使用，而每一个步骤都需要极度冗长的研发时间。
2.科技树上有大量完全无意义的科技。例如化学火箭科技树，又臭又长，需要极长的科研时间的同时，作用几乎为0。而且有部分科技单纯只能作为其余科技的前提条件，实质上完全没有任何作用。
3.资源点的数量和分布严重不符合现实，月球作为与地球一同诞生的天体，理应具备类似的成分，但是本作中月球的金属矿藏为0，其余天体也各有错误。同时各种资源储量严重不符合现实，地球居然只有一千四百万吨液态水（14MT），而现实中地球海洋有1.4x10^18吨，中间差了11个数量级。
4.地球化改造难度被不现实的极大缩小，正如之前所述，因为星球环境与资源数量挂钩，而资源体量少了11个数量级，导致地球化改造不现实的简易，而资源点却反而极易枯竭。
5.资源的消失，化学燃料（本作全部默认为液氢液氧）在火箭发射中被消耗后，本应进入环境中，增加水的存在，但是本作中其会凭空消失。从金属氧化物提取金属矿石，其中的氧元素也凭空消失了。
6.强制地球化改造的危险度机制，水星、金星、木卫一Io以及气态巨行星们被以“过度危险”直接拒绝了载人登录，但是科幻构想中已经提供了大量诸如“蘑菇城市“（蘑菇形的头顶反光材料的水星城市），”漂浮城市“（漂浮在金星高层大气的城市），”吊灯城市“（以类似太空电梯的方式吊入气态行星大气层的城市）等解决方法，而无需直接地球化改造.而本作作为科幻游戏却完全没有这些概念
7.一些诸如无法设置自动化人口摆渡，有限运输量，自动化拖拽可运输模块之类的QoL问题

游戏体验评分：7.5/10
这是一款品质相当出色的航天模拟经营游戏。作为该题材的爱好者，我认为《Solar Expanse》在玩法设计上集成了诸多亮点，内容丰富且颇具深度。不过鉴于游戏尚处抢先体验（EA）的早期阶段，部分系统仍有较大的优化空间，细节亦有待打磨，整体而言属于"未来可期"的优秀潜力作品。

游戏优化建议：
1、强烈建议增设"自定义闹钟/提醒列表"功能。 玩家急需一个可自主设定的定时提醒或自动暂停系统。在目前的游戏中，因专注于其他事务而错过最佳发射窗口，导致任务需等待数年之久的情况屡见不鲜，尤其在远距离载人任务中，这种体验极为挫败。

2、优化航天器的航行规划与任务设计界面。 建议开发一个集成化的任务规划面板，允许玩家在单一窗口内编排完整的任务序列，并实时预览各节点的轨道参数与预估消耗。这使得玩家能更便捷地规划包含多次霍曼转移与引力弹弓变轨的复杂航线。当前系统需在多个独立窗口中逐一创建节点，且缺乏对全程燃料消耗的总览，经常导致在后续步骤规划完成时才发现燃料不足，进而不得不逐个取消已设指令——这种操作逻辑对体验的破坏是巨大的。

3、新增全局航天器管理列表，并高亮显示载人飞船。 由于航天器数量增多后难以追踪其具体方位，经常出现宇航员因补给耗尽而意外死亡的惨剧。一个直观的选择列表将极大地缓解这一问题。

4、重构"任务清单"中的"周期性任务"模块。 前期任务稀少时该列表尚显清晰，但中后期大量周期性任务堆积会导致信息呈现极其冗杂混乱。目前需要逐一点开修改项才能查看具体内容，效率低下。建议参考游戏中"天体列表"的层级设计，将周期性任务按所属天体归类收纳，并在层级顶部展示汇总的运输吞吐数据，以提供宏观视角。

5、检查并优化电磁弹射器的重置/冷却机制。 目前该设施似乎存在逻辑异常：在执行从月球至命神星（Fortuna）这类远距离弹射任务后，系统会长达四到五个月无法再次使用。若这是设计上预设的冷却周期，建议在设施界面中明确显示倒计时或状态提示；若为程序错误，则需尽快修复，以确保玩家能够合理规划后续发射任务。

游戏内容建议：
1、深化天体资源与探测系统的联动。 制作组为了游戏性对资源分布做出了调整可以理解，但目前的衰减曲线略显失衡。通常在2070至2080年代时，地球与月球等大型天体上开采系数高于0.1的富矿便会全面枯竭，导致玩家被迫铺设大量高维护成本的低效工厂。而此时的科技水平下，小行星采矿的往返周期过长、运量杯水车薪，完全无法填补资源缺口。建议后续通过增加科技树选项（如深空开采效率）或深化探测器玩法来优化——例如探测器可触发随机事件，揭示新的矿脉或解锁特殊增益。

2、引入进阶航天运输机制。 为了丰富中后期的物流策略，建议考虑引入"天钩系统"（空间动量交换绳系，Space Momentum Exchange Tether）等概念。这类设施能在天体间构建起自动化、低能耗的物流网络，极大地提升运输效率与游戏趣味性。

3、丰富商业合约系统与阵营玩法。 中后期由于缺乏有效的资金回流手段，极易陷入破产泥潭，尤其是对于不习惯手动关停冗余设施的玩家而言。建议增设由各大阵营或地球联合政府发布的周期性合同。例如：发布建造巨型空间站的全球招标，各大阵营根据建设贡献度瓜分最终奖励。这不仅能缓解经济压力，也能赋予中后期更多的目标感。

Gameplay Experience Rating: 7.5/10
This is an exceptionally well-crafted space simulation and management game. As a fan of the genre, I find Solar Expanse to be a comprehensive work that integrates a multitude of intriguing design mechanics. However, given its current Early Access (EA) stage, several areas require further optimization and content enrichment. It is definitively a title with immense potential for the future.

Gameplay Optimization Suggestions:
1、Strongly recommend adding a customizable "Alarm/Reminder List" feature. Players urgently need a system to set timed reminders or automatic pauses. Currently, it is far too easy to miss an optimal launch window while micromanaging other aspects, resulting in frustrating delays of several in-game years—a critical issue for long-distance crewed missions.

2、Optimize the mission planning interface for spacecraft navigation. An integrated flight planning panel is essential. This would allow players to sequence an entire mission manifest within a single window and preview relevant data for each node, facilitating the efficient calculation of complex trajectories involving multiple Hohmann Transfers and Gravity Assist maneuvers. The current workflow forces players to create nodes in separate windows without a global fuel budget overview. This often leads to the frustrating realization mid-planning that there isn't enough Delta-V, forcing the player to manually cancel every individual node—a poor user experience.

3、Implement a global spacecraft selection list, with a highlight option for crewed vessels. It is currently too easy to lose track of ship locations, leading to the unfortunate (and frequent) starvation of astronauts due to logistical oversights. A dedicated management list would significantly improve oversight.

4、Refactor the "Periodic Tasks" section within the Mission List. While manageable early on, this list becomes a cluttered and incomprehensible wall of text in the mid-to-late game due to overlapping cycles. Currently, one must click into each entry just to see basic details. The UI could draw inspiration from the in-game Celestial Body List by nesting periodic tasks under their respective astronomical bodies and displaying aggregated transport statistics for quick reference.

5、Review and optimize the reset/cooldown mechanics for the Mass Driver. The facility currently exhibits what appears to be a logic issue: after executing a long-distance launch from the Moon to Fortuna, the system remains unavailable for four to five consecutive months. If this is an intended cooldown period, a visible countdown timer or status indicator should be added to the facility interface. If it is a bug, it should be addressed promptly to ensure players can plan subsequent launch schedules reliably.

Content Development Suggestions:
1、Deepen the integration between planetary resources and probe mechanics. While I understand the developer's adjustments to resource distribution for gameplay balance, the current depletion curve feels unrealistic. Around the 2070s-2080s, high-yield deposits (extraction coefficient >0.1) on Earth and the Moon become completely exhausted, forcing players into a maintenance-heavy grind with inefficient factories. Concurrently, asteroid mining at the available tech level yields minimal returns over extremely long transit times, failing to offset the deficit. Future updates could address this with advanced tech tree options (e.g., deep-core mining efficiency) or by enhancing probe utility—perhaps triggering events to discover new mineral veins or unlocking unique boosts.

2、Introduce advanced space logistics mechanics. To enrich the mid-to-late game, I would love to see the implementation of concepts like the "Skyhook" (Space Momentum Exchange Tether). Such infrastructure would enable more automated and highly efficient transport networks between celestial bodies.

3、Expand contract variety and commercial gameplay loops. The current mid-to-late game economy often leads to bankruptcy due to a lack of robust income streams, especially for players who forget to mothball unused factories and ships. Adding periodic, small-scale contracts from other factions or a "World Government" would be beneficial. For instance, a global tender to construct a massive space station where factions earn rewards based on their contribution percentage would provide both financial relief and a renewed sense of purpose.

目前最大的问题是，作为一款模拟经营作品缺乏收入的正向循环。
游戏的收入主要依赖任务奖励，在火星殖民后，动辄几年、几十年的任务周期，很容易资金链断裂。
贸易作为收入来源很容易陷入“水多加面，面多加水”，建立资源供应链→火箭维护费提高→缺乏收入→更多资源供应链→火箭维护费进一步提高→进一步缺乏收入，而且ai的贸易需求很不稳定，靠老天赏饭吃。
星球殖民作为核心玩法，缺乏正向收益，可以考虑让外星球的人口产生实时的资金收益

The biggest problem at present is the lack of a positive cycle of income as a simulation management game.
The game's revenue primarily relies on mission rewards. After colonizing Mars, with mission cycles often lasting for years or even decades, it is easy for the financial chain to break.
Trade, as a source of income, is prone to a vicious cycle of "adding more water when there is too much, and adding more water when there is too much". Establishing a resource supply chain leads to increased rocket maintenance costs, which in turn leads to a lack of income. This, in turn, requires more resource supply chains, further increasing rocket maintenance costs, and further reducing income. Moreover, AI's trade demand is very unstable, relying heavily on luck.
As a core gameplay element, planet colonization lacks positive returns. Consider generating real-time financial income for the population on outer planets
