Bah, lost six or so games in a row now. I get confused as soon as my pool and second hatch finishes, can't decide on a tech route and my macro quickly falls apart at the 30 drone mark or so. Frustrating!
I'll keep fighting though. I think I'll make a better effort of scouting my opponent early game and if only a few units are out make a round of lings for a quick attack while planting a roach/baneling nest, else make fewer and plant roach+evo and tech to lair asap.
Edit: Oh right, finished the campaign. Most fun I've had in single player since Skyward Sword and much better than WoL's. The only thing I didn't like was the white washed Queen of Blades-impersonation they had on screen.
