UO 2 (only if it's old UO with more skills, a bigger world and a nicer engine which retains the original viewpoint)
Homeworld 3 (only if it's all the best parts of Cataclysm and HW2 put together)
X-Wing vs. Tie Fighter 2 (updated engine, online multiplayer)
Lineage III (lets actually get rid of the bots/farmers this time though eh?)
Dune 3 (Dune 2 remade in the same way as Starcraft was remade)
Sensible World of Soccer 2 (original gameplay, online multiplayer)
Guardian Heroes 2 (original gameplay, updated engine/graphics, online multiplayer)
That's off the top of my head, I think it's a rather tasty selection.
