It's lightweight but that doesn't equate to "weak" by any means. It's satisfying, like a Paper Mario. Maybe it's a weak RPG, but as a game it's strong as hell.
I agree. I think if they removed the South Park and created even a half-decent world, storyline and characters to go with it, it would still be a great game. Of course, as a South Park game, it puts it over the top.
Whatever the case, it's $20. Still well worth it x1000. I would have bought it right away, but I already had it on PC and played through it multiple times (purchased full-price on release day and well worth it). But I was going to buy it and have it on PS3 as well.
