That's far harder to do right than graphics and it's going to have a bigger impact on how immersive the game is. You can always improve graphics down the line but getting the mechanics and handling right is a lot more important and will be a lot harder to change later on.

Graphics, yes. But the actual gameplay... a joke compared to the first Rainbow Six and tactical matches on SWAT3.
Linux Air Combat on the other hand really does look the way games looked 30 years ago, and the UI looks worse.
It's fine, we don't need good graphics in everything. But it will hurt its popularity in a way that Battlebit is not hurt, because people can tell the difference between intentionally making a game with a retro look vs. just not having the art resources for good graphics.
It looks like Roblox Battlefield.
The only real complaints on an otherwise ridiculously overwhelmingly positive Steam page seem to centre around the anti-cheat.
The MinSysReq also suggests it'll run on a potato, so it sounds worth a shot!
Amazing how low the bar is for AAA games in terms of gameplay and fun.
