Lately I've had a hankering to play something with an open ended, freeroaming world, which a bunch of stuff to do, kinda like San Andreas, but I've been out of the loop for a while on current games, and I have no ideas what, if any newer games are like this.
So I need some suggestions, it doesn't have to bloody or violent or anything like that, I just want something mission based, open world, with a bunch of fun minigames and sidequests. If it features a huge map and character customization like SA that's a plus. Also it needs to be on either PS2, GCN, or DS, cause that all I have at the moment.
Also to prevent flamewars and smart alecs, I'm aware that GTA did not invent the idea of this trype of gameplay, I just used it as a example becuase it's the most popular and universally know game in that type of genre.
