@DaetherX Very, very few robots are missable in SRW 30, and I believe the only missable characters are all recruitable villains. DBD missions are almost exclusively DLC related, with a handful of them being free updates tied to the DLC, units and pilots from them generally have less story integration, and are not missable under any circumstances.

For both you and everyone else I'd suggest looking at a website called Akurasu. Its generally the best source of information for ALL Super Robot Wars games, and for this game in particular it has a detailed flowchart that includes what missions block others, but places those missions in the order they appear in the game rather than alphabetically, and tells you not only what those blocked missions unlock, but if those unlocks will be missed by not doing the mission or not. In the majority of cases they aren't, you just won't unlock them until later.

Man, as a newcomer this is SO intimidating.
Specifically I'm curious if any single mission might block a series of missions. Like if "Mission 1" introduces SuperCoolRobot but then will block "Mission A" (that would also introduce SuperCoolRobot) but if you take that one it would lead to "Mission B" which leads to "Mission C" - mini-story-arc complete.

It's also a bit overwhelming as I'm not familiar with any of the super robot shows outside of Gundam, having only seen trailers / clips of some of the series in the game, and not knowing which mission names might be telling me what MS/SR I'm going to get from them but I don't know because I'm not familiar with any of them so any key words are over my head.

I have like half a dozen or more DBD missions right now, just arrived on Earth. I did a few in space where 2 spelled out exactly what mech I was getting in the description when I visited the area. Sorry if this was ramble-y.

@Thundercraft

Yup, that was made by a very cool guy (me).

For walkthrough, the best you get is the wiki: https://akurasu.net/wiki/Super_Robot_Wars/30

Not like the game is challenging enough at all to require stage-by-stage advice.

On NexusMods I found a mod called "SRW30 Unlock All Missions", which does exactly that: All missions are unlocked by removing all pre-requisite flags. And I thought I would mention it here for anyone interested since it does seem relevant. I know I'll be using it.

Now, if only I could find a full or even partial walkthrough...

Yeah, I believe it.

I got to a 10 column wide chart, with lines going all over the place, before even finishing up the first act of the game.

I'd believe it would be complicated. Some missions will become unavailable to do simply because you are forced to go on that mission, but, it will have a different name. So, the flow chart would have to also take into consideration those missions. Plus, not all missions pop up at the same time, or in a timely manner that would help make the flow...well....flow. But, yeah, it would be a very complicated flow chart.

I tried making a flow chart. It's even more complicated than you'd expect.

While incredibly useful, this list is also incredibly complicated and hard to follow.

Instead, I really wish someone would take this information and create a proper flow chart in a paint program, graphically showing which mission is connected to which. (In other words, a proper flow chart like that used in software and game development.) That way we could simply look and decide at a glance which path in the mission chart to follow to do certain missions or achieve certain results.

BTW: I've actually created a flow chart like that for a complicated game similar to this.

That said, I know it's a lot to ask, especially since it seems nobody has yet to publish a proper Walkthrough FAQ for this game, even though the game has been out for over 5 months now...

What I found that worked for me was to do all the missions that did not have stars next to them, as the starred missions advanced the story. That way, I was able to complete lots of side quests.
