Terraria, I just can't get into it. In my circle of friends, they loved this game and played the crap out of it. We played together a couple of times, but I just couldn't get going.
And Final Fantasy VIII is really popular. And I just don't get it. I like, like three of the main characters. The music is good, but everything else is just not for me. And my cousin has VIII as his favorite in the series.
