The GTA games for me since VC have really been kind of hit or miss. I play them for a little while, and then dump them. GTA3 is still my favorite, because I actually enjoyed the storyline, and the game was just more fun to play altogether. For me, anyway. But watching this trailer actually gets me excited to see that the game might actually have a compelling storyline, and the Russian Guy seems pretty cool. For some reason, it reminds me of Max Payne. I also think it's refreshing that they didn't just try and create another city, and I figured they would run out of ideas anyway. It'll be fun to see Liberty City on the PS3, and it looks like it's going to be more NYC-oriented.
As an aside, I really hope that they bring back the Classical station from GTA3.
