The trailer I saw of the South Park game had me laughing for it being "South Park", so yeah. I can definitely see why people would be looking forward to it. Might not be what I'm looking for specifically, but it has the South Park look and feel to it with the humor and the dialogue that I heard from it, so it certainly has its appeal + it also depends on what people think of Obsidian, a company with a divided fanbase to say the least after FO: New Vegas.
I'm personally looking forward to Ni no Kuni myself. The demo was fun, and it looks downright amazing. Studio Ghibli did a fantastic job with the visuals behind the game, and the gameplay for it was pretty good from the bit I played from the demo. Overall, I can see the appeal of both games (Especially for South Park fans looking for a good game in that series), but I myself lean toward Ni no Kuni.
You're casual if you like anything. Real hardcore gamers hate everything.-CyhortI82
