Total Annihilation, Command and Conquer, and Dune 2 - in that (descending) order.
I never really got the deal with Starcraft. First time I played it I just thought "Huh. It's Warcraft 2 with a new graphics skin." - I know there are more differences than that, but you know what they say about first impressions and all. Every time I play SC I get the nagging feeling that the best counter for a Zerg rush should be a force Paladins backed up by arrow towers. And that peasants wouldn't be able to breathe in space.
