Probably too many since I made it all the way up to a few days into teraforming. But I knew I was going to constantly be bothered by the location of the plaza and eventually give in. I know myself too well in that regard. I have too much fun with this game and enjoyed even the beginning days so it wasn't too painful to reset. I'm happily almost caught up at this point, I'm getting my first camper tomorrow! ^-^
