No PS2. I have a wii with homebrew, a psp with homebrew, and a non-homebrew xbox 360 and that's it.
I could finish up the last 20% on all of my 80% finished games. Generally when I'm done with the main story I am done with the game, as the story is almost always the only driving factor.
Don't get me wrong, I do a lot of exploring DURING the story, but after the main story is done I typically can't find the motivation to return and find every hidden thing.
