I find the best way to get better is to just play a lot against people who are a little faster than you, and day by day, you will get a little bit faster as well, and learn how to be aware of builds, maps, upgrades, scouting, expanding, and unit positioning, all at once. Soon, it will be consolidated into your gamer framework, so while you're giving your units actions, or even fighting, you can still manage your bases and the rest of the map, while still being able to monitor the action.
I guess I might have to cop SC2 then. Like you say, the difference in skill between players can be massive and seem overwhelming. Once you start losing and don't know how to improve, it's hard not to quit. I might start watching more gaming streams to get better. Does that strategy help?
I have several PC titles I regularly play including the Arkham Asylum series; a medical surgery stimulator; Darksiders 2 and Dishonored. Moreover I'm a Halo stan![]()
I also would watch vids of the top players to see how they played. I learned the reaver/shuttle tricks from grrr... who was a beast at it. Obviously, I wasn't as good at it as him, but I became proficient enough at it that I could win against entire zerg and terran armies with a 2 shuttles, one filled with reavers and one filled with templar, 12 zealots on speed and weapon upgrades, and 8 dragoons. I'd also bring a few probes to build pylons and set up shield batteries in enemy territory during fights, and rotate my dragoons in such a way as to keep all of their shields up, while pulling the enemy toward the shield batteries, where I could keep my units alive.
It's funny, when I played Starcraft as a kid, I used to type 80-90wpm. Now that I don't PC game, I struggle to type about 60wpm. Transferable skills from gaming, brehs.
