It has a hell of a lot of new weapons (that are worth using), The AA-12 with explosive shells being my favorite. The missions are decently varied. I liked the story a lot more. and you can replay any mission once you've beaten the game. and sort of go for a better percentage. The only thing I didn't like so much were the helicopter missions... but only because I suck at PC controls for heli's in GTA. The entire time I played I think I got 1-2 calls to go 'hang out' (and there are only 2 characters to do this with, and you do it with both) This is a plus.
Yeah in general I enjoyed this one quite a lot. also Brucie is in it.
Though IDK if you should envy that I am playing it on PC. As it suffers from the same low FPS and pop-in and GTA4. It didn't bother me to much because I'm not picky about that sort of thing. but many people are.

Spoiler Talk involving GTA4, TLAD, and TBoGT:
Hidden content (Click to reveal)TBoGT is the only part of GTA4 that didn't have a bittersweet ending. It was pretty much just happy. Also, I forget, but the Russian guy you kill at the end of TBoGT, is he the guy that was originally after Niko? if so then that makes Niko's story somewhat less bittersweet because then he doesn't have to deal with guy himself... its just that he doesn't get to find this out so he'll be looking over his shoulder for the rest of his life if he never finds out. Though I suppose he might figure it out. BTW I got the roman lives ending in GTA4.
