I find the Asian beta to be the most interesting one. 2009 build, to be precise.
The later 2010 stuff, I played myself. It's a lot closer to the game that's played later on.
I guess "Tier 1/2/3" for cars, or those "cops" on streets.
But the 2009 build was almost a completely different game.
Visuals, I swear... it looked better. When I try to look at a few images and do comparisons it looks a lot more clean compared to the later builds.
The UI elements looked more simple and modern, instead of that 3d missmatch of glowing colors everywhere.
In the end, only the UI, not talking about the rest since there's a lot more going on there, it became a complete mess of everything.
They should've kept it the way it was.
Still though I guess it's aight the way it turned out in the end ayy.
