Personally I prefer to play starcraft with a custom map which cuts mineral piles down to 1/3 or 1/4 of normal, and has event triggers to convert gas into minerals when gas > minerals in storage.

Makes it much more interesting, and takes longer too. Territory is actually worth something, instead of just the main enemy base.
You can make use of special abilities...
And the biggest units are actually scary.
