I was thinking of implementing a concept where at one expansion, instead of regular 1500 mineral patches, you could replace them with 250 stacked 6 mineral patches. This way, at that expansion, you gather 6 minerals instead of 8 at a time. Of course this causes a problem that's shown in STALKERANOTHER where it's actually used as a map feature. Still it could be used. Perhaps make unbuildable terrain under the mineral patches.
I was going to make a map with this but I can't think of anything I could do that someone else couldn't do better with this concept.
You'll get a huge number of units in that map. Say the expansion will have 5 such stacks. 2 Players, so 10 stacks. That makes 14x250 = 2500 mineral patches.
And - drums please - here comes the problem:
SC has a unit limit of 1700. 2500 > 1700. Bad.
You would want to have at least 400 unit slots per player in 2 player maps (lotsa mines in tvp, mass lings in zvz), so you should limit yourself to 900 neutral units on a map.
In 4 player maps you could probably put about 700 units or so without running into problems, since 2v2 rarely goes into huge lategames.
Another issue: Such stacked minerals will favor p and t over z immensely. That is because even though you can only mine 6 minerals per worker, many workers can mine at one stack at the same time. Since z is low in worker numbers, it won't have the chance to use this opportunity.
Would it balance it out if the expansions actually had only a few minerals so that it would be most profitable for Zerg who need to place an extra hatchery anyway? This could also help out with the unit limit problem.
Well, I don't see anything great coming from such a setup. Maybe you can balance it out, but then it most likely will behave almost the same as a normal expansion.
I don't know how it will work out exactly, so don't let me stop you from trying it out. Just be aware of the unit cap.
Sorry I meant 'change' not 'chance'. I'm assuming what you did is just stacked 6 count mineral stacks times X mineral fields that equaled to 1500 or something.
That's bad imo, stacking workers is not good for melee play, splash damage worker drops become 10000000x more effective.
