You've probably heard this before, but my suggestion for the suggestion box is:
PLEASE MAKE A FANTASY RPG BASED ON THE M&M RULES!
I'm a fan of D&D 3E and d20 Modern, but I just LOVE the M&M rules. With a system of wizard / cleric / druid / etc. "super powers" and extras, you could have an excellent class-less/level-less d20 FRPG!
