#17 Jack & Dexter: The precursor legacy played on PS2, released 2001
My favorite action platformer of all time. Great visuals, great variety, great characters. I really can't think of any flaws in this game. The seamless world with no loading times still is a technical marvel.
All the different worlds are well crafted with plenty of fun characters and things to do. Games like this are sorely missed this gen.
I'm looking forward to playing the HD collection in Februari. Maybe I'll even grow to love Jak II and 3 this time which were overshadowed by the much more fun to play Ratchet and Clank sequels back when they came out.
