I like the sounds of this already to be honest, the setting of it looks pretty good. Sounds like they'll be tackling some of the racial issues that were rife around that time period.

Gunplay looks very similar to Mafia 2 (looks better in motion than the screenshots suggest). Judging by the IGN interview it sounds like they'll be making up for some of the areas that Mafia 2 was definitely lacking in.

Looking around at the reaction at other forums and stuff, very reminiscent of the response when CJ was unveiled as the playable character in San Andreas
