The game has changed a lot since GTA3 days... The story is pretty interesting in the latest one, with memorable and unique playable characters (you can play 3 of them, switching from one to another as the story progresses), plus they have tried to borrow some elements from other games like RDR and Max Payne. And it's not too difficult this time - for example the driving has improved by a great degree compared to previous games, same goes for flying and other activities. Really worth it to play through at least once, though I personally will wait for a PC version - the low resolution of in-game textures is really noticeable nowadays and the PC version should improve that.
