Continuing on the magic vein, what would be great would be a game with no pure offensive magic whatsoever. No fireballs, no lightning bolts, no frost versions of fire spells. D&D did a lot for this sort of magic, and it would be wonderful to see a game where all the magic was stuff that could be used offensively, but only if you were creative with it, a la Grease. Not the shit Bethesda tries to pull with the pure support/useless Illusion, Mysticism, and Alteration school spells, but spells that could be used to solve problems in unconventional ways, even if some of those problems happened to be carrying swords.
Eh, for that matter, how about Air spells that are more than just plain damage and knockback/spinning. Let's see air spells that don't do damage directly, but can cause secondary damage by smashing enemies into or off of things, that can break through windows and doors, that can move items around in a less controlled manner than telekinesis. Let's see tightly controlled spells to snuff out candles and lanterns for a stealth character.
On another old complaint: GTA 4 SAVESTATES. HOW FUCKING STUPID- Oh, I can only save by starting/completing a mission or driving halfway across the city to a safehouse? Just great. Exactly what I wanted, a game that takes fifteen minutes to save.
