Haha, this is weird. I only started playing this again a day ago after completing it about a year back. Its a good game, but I think its getting dated now in the graphics department. Physics and story though is amazing, and its definietly worth playing.
Like me, you'll probably go back to it too. I don't have a wanting to buy Episode 2 though. At least yet.
I don't honstly think it was the right way to release them, but at least they aren't rushing a full larger game.
