Yeah I got the idea watching my GF playing Plague Inc obsessively and she never plays games. The idea is basically two players are playing on a globe instead of just an individual map like SC. You set macro-level AI on each individual sector. Lets say there are three: Defensive, Offensive, Economical. The AI would execute your high level order and each zone would generally just be AI vs AI. You wouldn't see what your opponent set so like Offensive > Economical > Defensive > Offensive. You would have tech trees to unlock that would cascade to all your sectors similar to Plague Inc. So like if you set generally to offensive you'd want to rush weapon upgrades, if you rush defensive you'd rush building upgrades and the like. So that is the "simple to play" idea.Thanks Tenks!
That sounds cool just from the "x + y" concept. You should pursue it if you can, even if it's one hour a week, it'll be more likely to get done (or far enough to see if it'll work) than never working on it.
The "difficult to master" idea comes from you can, at any point, take control and become to commander of any zone. That is where the Starcraft comes in. Each zone is basically a self contained Starcraft match. So if you see you set yourself to Defensive and you scroll over the map and see your opponent built command centers at every resource patch you can just click in, build some units and go attack his stuff. The game would be a fast paced RTS like SC. But you won't want to sit in one zone too long. Lets say there are 50 zones per globe. So you can obsess over winning an individual zone but it would be smarter to perform some hands-on actions in one zone, exit to let AI take over and jump to another zone to get hands-on.
I think it sounds like it would be fun because it has an accessible way of playing by focusing more on macro management and the skill tree and rarely taking command. Or if you can play at 500 APM and evaluate situations quickly you can keep jumping in and out of zones.
Way too much work for me to really start on and I don't know the first thing about using Unity or any other off-the-shelf game development project.
