What you want to do is play against 3 AI on Insane difficulty using a trainer that gives infinite minerals, infinite gas, infinite units, instant build, instant unit/tech, infinite unit power, no fog of war
Somehow i still lost one game, but thats because even with a trainer i am kind and dont attack them for a good 30 minutes and when i do attack them i make sure my forces are evenly matched. But the killer move they made was sending three huge attacks all together, i thought my defences would hold out. I had like 50 tanks, 10 thors, 100 marines and a load of other things. But they beat through them and i couldn't click quick enough on the baraks (literally
) to make enough units to kill them once they got into my base. Anyway, it was hugely fun.
But i have found a problem with the game, last game i was playing without the trainer against the AI on medium for a nice relaxing game where i could do a bit of good base building. I was getting minerals and gas across 2/3rds of the map and had ~60SVC's so it was a pretty big base if you want to call it that, i also had a similar amount of units. But all of a sudden, the game would stutter in the exact same way every second or so. It didn't look what i would call a typically low framerate, but anyway i turned eveything to lowest and the problem still existed. I saved, exited the game, shut down all the other programs i had open and made sure no intensive tasks were running. Started the game back up, loaded my save but still no luck - a half a seccond stutter every second. Totally unplayable and highly annoying.
