All I want is for the Sci-fi simulation games to return. Oh how I mourn the loss of games like X-wing, Tie-fighter, Wing Commander, Freespace, Mechwarrior (okay not exactly dead but MW5 was delayed indefinantly). All we get is weak mouse driven crap like Freelancer.
Adventure puzzlegames are another genre I want to see make a comeback.
Genres I would like to see shelved for a while are FPS's, and racing games.
Keep dem RPG's and RTS's coming!
