TBH I don't care about other strategy games despite their ease of use because they simply don't have the depth, balance, and effectiveness instilled in every action.
I'm a Terran player.
I haven't really gotten too deep in the metagame, I've only played 3 ladder games (won them all), and a couple against buddies. I'm not even gonna think too much about midgame strategy aside from infantry + tank push, until I master early game- so basically all I know is openers and cheeses right now. I'm liking Reaper Harass into Marauder/Tank, as I can't really get Full Mech or 1/1/1 to work.
Hands down my favourite build is Planetary Fortress Rush. I pulled it off against my friend today. Get an engy bay, save up 150 minerals and 150 gas, fly over your Command Center (load some SCVs into it) and your Barracks. Land them into your opponent's base. Start transforming your CC ASAP, and use Marines and SCVs to take out Marines or Zealots. Blast the workers, then blast the Pylons (if Protoss) or just go straight for the town center. It's a horrible horrible strategy, but you opponent's surprise just MIGHT let it succeed.
