How bad are the microtransactions in this game?
No idea because I've never even looked at the online store for any game I own.
At lunch time I went home and fired up the PS2 version... and found some differences in the presentation... stuff I didn't expect actually.
In the X360 version some of the cutscenes feature CG versions of the drivers in their cars, the first blocker you meet there's a cutscene with him pulling up to you and you see a polygonal version(really good one actually) of him including his face talking to you from the drivers seat of his car(as oppose to other cutscenes where you'll get the real person "in" the polygonal car.
Of course the graphics take a hit on the PS2 but the game actually looks similar to Underground 2... and more interestingly the sense of speed seems to be higher.
That's distinguished mentally-challenged.
