I have a lot of respect for GTA2 but at the same time I didn't enjoy playing it that much. It's all about the setting. Intro showed some cool action set in the present-time city - just in the spirit of GTA1 who sadly hasn't aged very well - but vehicles made me think of some kind of dystopian, retro-scifi setting. It just felt too awkward for me. If there was a GTA2 mod that introduces "common" cars (and probably GTA1 cities, which I loved) then it'd be a win-win situation.
