Burnin' Rubber 6 is looking to be a worthy successor to the previous and much older games in the series. It certainly needs more work in it's current state though, and there are several glaring problems and a large amount of unfinished content. I can clearly see the bones of a good game here, there just needs to be many changes and additions to become a truly wonderful game.

Issues with vehicles and weapons:
The turn speed on vehicles do not scale with current speed, so when you are at low speeds, you have an extremely slow turn rate that requires you to back up a large distance to go around any corners you may hit.
The normal turn of your vehicle doesn't have any speed tradeoff, unlike most other games, while the drift has massive speed loss, making it far worse to use over any extended period of time.
There is also no ramp up time for turning currently, which causes problems when trying to aim precisely when moving at higher speeds. I believe the default turn should slightly decrease your speed/acceleration, while the drift should have a marginal speed/acceleration increase from it's current state.
The turn rate of the truck used in the elimination mission has such an extremely slow turn and drift, so much so that it is nearly impossible to complete the track without hitting every wall you try to turn at.
There is currently no invulnerability when respawning, meaning you can be wrecked and respawn only to be immediately wrecked again.
The minigun weapon currently has no wind up speed, and nearly perfect accuracy, which feels off for both the type of weapon, and the game feel.
Some weapon mounting locations in the game do not conform to the vehicle, resulting in floating sections which could be easily fixed just by adjusting the angle.
Certain weapons used by NPC drivers currently cause large lag spikes when the projectiles explode.
I personally also believe weapon ammo count is too high when factoring in the amount of ammo refill upgrades along each track, there should be a tradeoff for ignoring ammo refills and going purely for nitro refills.
Health feels good in it's current state, though certain weapons damage seem a bit overtuned for how much health the default vehicles have.

Issues and concerns with maps, geometry, and physics:
Of the maps I have played, none have had alternative routes or shortcuts to take, I hope these will be included in the future.
This is a personal dislike, but I believe the cars feel stuck to the ground and do not get the airtime possible in previous titles that made jumps feel so good to use.
I do believe wrecked objects have their physics tied to fps currently, which can cause problems when running the game at higher fps like for my 165 hz monitor.
Several objects on each map seem like they can be passed through to wreck them and keep your momentum, but this is often not the case, resulting in you losing all of your speed almost immediately, wrecked cars also have this trait.
A certain jump using a dumpster on one of the maps has wonky geometry and has caused my vehicle to get stuck on the edge more than once, and there is currently no way to self destruct/unstuck your vehicle.

Performance issues:
The realtime lighting system currently in the game does not work at all, it brings my RTX 4070 Super to 6 fps and constantly freezes. There are also some other minor issues with freezing outside of realtime lighting, presumably due to loading assets like a certain billboard texture on the first map I tried.
Load speed seems quite unoptimized in the current beta, I am running the game on a M.2 SSD and it is often taking more than 10 second to load into each map on the lowest settings.

Audio and menu issues:
Audio mixing is a bit off, but the classic sound design fits quite well with the style of the game. Though some of these sound effects do certainly feel like they are from 2010 and need updates/replacements.
There is currently no way to mute the game while tabbed out, and you can still interact with menus while doing so.

Unimplemented content:
I do believe open world will be added eventually, similar to Burnin' Rubber 4, my personal favorite title in the series by far, but it is unimplemented in the current demo.
Vehicle customization is also currently unimplemented in this beta, which I believe will be added in the future. I do hope you will be able to customize car components, and not just weapons/paint.
Due to vehicle customization not being implemented, there is currently no use for the game's currency, this should be resolved in the future.
There appears to be a currently useless leveling system, I presume this will be used to unlock new vehicles, parts, and weapons to buy in future versions.

I hope that the devs will continue working on this game, for I see massive potential in it, and it is already in a very playable state. I am certain I missed things in this demo, but I will be coming back to it at a later, more finished state.
