@Tauren, I agree but I think that would need to be done on a new server rather than this one.
@Foulsham, Im ok with it being a project that costs like 10 bucks (same with i tech for infra). I dont think you should get to keep planets though. Literally just x percentage of infra, making it like a boosted restart. I could also see an argument for keeping artifacts up to the maximum current caps (so if you had grandfathered pile of artis, youd lose any over current max).
I definitely think its a fine idea. If youre losing everything but infra and maybe some artis, I could see it being worth the purchase without being really abusable. Like if someone decides to change rance once a week, its not really hurting anyone, and the game devs can make a few bucks off them.
On a similar note, I think requirements for i tech library (change infra) should be lowered. The turn requirements for a high infra player are frankly absurd. Drop the turn requirement massively and just make it 30 day or 60 day cool down or something instead.
