I got little game called Factorio - yes yes, everybody and their engineer uncle already playin it.. to be fair I knew about it for a long time but it was always "this looks meh" kind of thing. I was wrong very very wrong. Since the last week I am glued to my screen building true spaghetti monster of a factory. Done all new Factorio player mistakes one by one but learning a lot!
Its one of those games where I know I will be coming back to it on and on since every playthrough will be completely different. Its truly amazing.
Sounds like you've been infected by the building creator bug. Might want to consider Satisfactory or Cities: Skylines in the future. Both of these are constructing civilization megalomania on 'roid rage
