I played it for a week straight and really liked it. Clever, humorous, and a fair amount of action, too. Very good game. Not great, but I always appreciate it when a game developer tries something a little different.
I'm totally there right with both of you guys. While I didn't play it through to 100% (since I heard there isn't any cool reward for it) the game was awesome! Creative design, rich characters, awesome script, great music score. Not the greatest game of all times, but definitely a great game and worth playing for anyone who's into free roaming games.
I probably never will. I mainly play strategy games, so I'm pretty happy with my PC. Most of the other games I play (sports, GTA etc) get ported to PC eventually. Besides, I own enough electronic gadets already!
If I were to buy a console though, it would probably be a Wii, simply because they've done something different.
I wrote up a bit of synopsis/review here if you're curious.
If you've got a ps2/3 you should definitely check it out. Some good variety to a genre that's been around the block more then a few times, though I haven't heard anything regarding emulation.
