I don't know. WC1 and 2 would need a lot of work, both on gameplay and especially on narrative and presentation to warrant a remake. Not sure if it's worth the trouble.I am still hoping they will remake WC1 2 and 3 on the SC2 engine.
Probably StarCraft. Not only because it's more recent, but also because it's vastly more popular in South Korea and has a lot more attention in eSports.Is there some statistic about WarCraft vs StarCraft preference? I'm curious which RTS is more popular.
