lol this will all probably change in the next few months

The map editor is fantastic. I have spent hunderds of hours making my own scenarios back when I was a kid.

No particular order: Chrono Cross, Xenogears, Kingdom Hearts II, Uncharted 2, Donkey Kong Country 2... this is so hard, there are many more that I love :(
