Luft is pretty correct, I liked 1 and 2 a lot, I even liked SR2 more than GTA at the time, it felt more free and alive to me, there were more opportunities for goofy yet realistic fun. I got SR3 played it for about an hour, upgraded my weapons to a bunch of retarded shit that fired octopusses and crap like that and the game was just ruined, you couldn't even downgrade the weapons back to normal so I just gave up on it, haven't played it since.
