Hey, have you guys ever played Klonoa or Klonoa 2? I've played the latter, and it's awesome. Everyone who likes puzzle-platformers should check it out. I found a used copy for $20 in Gamestop ages ago, but it can be had for pretty cheap online via ebay or whatever.
I think for a while, Namco was trying to make Klonoa their flagship character (I guess he's more hip and mascot-ish than Pac-Man), though who knows why that failed, Klonoa has been a lot better than the last 3-4 Sonic games.
I've always wanted to play the PS1 Klonoa but I could never find it to rent or buy anywhere. I own Klonoa 2 and it is indeed a great game. A bit too easy but it's not really meant for an old audience. Great atmosphere in each level and a decent story too. The bosses are all fun to beat. I love those buttons that launch you a thousand feet in the air like the ones in Jumping Flash.
