Territory Idle

Territory Idle falls into the genre of TRIMPS. You buy things to create other things. If you like TRIMPS or are a little intimidated by it, TERRITORY IDLE might be right up alley. It is a very very steep grind, and everything you buy is extremely expensive, however with that said, be prepared to let the game "simmer" over night so you can upgrade.  There are many facets of this game I was not aware of at first, and much of it I will not spoil here. It is a free game (currently) from STEAM. Definitely worth a look

DO NOT let the simplistic look fool you.
