Elves, Dwarves and Orcs. Stop using them altogether. Invent some new fantasy races, for crying out loud. How about more fantasy games in which there are no humans, either?
Make more controller only FPS games, just to give the finger to those keyboard nazis.
More HD games, not less. Give the poor, tired, huddled masses who need to shelter around their 15cm screens, connected through RF converters something to work towards. A goal in life. And make that goal 1080p.
Unblockable/undodgeable attacks and other unpredictable death events that are only avoidable after reloading several times and studying the exact pattern of events leading up to said death.
More imaginative achievements/trophies. Killing 250 of monster X is a grind quest, not something to be proud of. Dragging that stupid fucking gnome across 5 chapters and 2 vehicle rides without losing the little prick is something to hold your head up about, while those around you just plain worry about what kind of weird OCD variant you must possess.
