Hmm, very reasonable. Actually when I think about it, 2k is too much. Maybe 1k. But I too would prefer your solution, but then that gets a bit 'scripty' and I'm not good at that. I'll put it down to 1k though, that is too much.

I like the idea of something that's a bit like this mod, just massively toned down. Such as +10 Minerals for the first 12 months, then +5 Minerals per month for the next 12 months, or something like that. This mod gives far too much, and it gives it all at once.
