Updated after Frozen Pack DLC
I really like that there are reasonably priced DLC's coming. $5 to expand the game another few hundred hours or more - or try a different base strategy. Updates come out regularly enough I can start about 2 bases a year or so, or just keep plugging away at old bases with new tech from DLC/updates.

My favorite game I own.

Really great evolution of the survival/base-building genre. Part SimCity, part Minecraft, and part sims. Once there is ONI (Oxygen Not Included), there is only ONI - until you have too many dupes or mismanage your base. :)

I can't wait to see what Klei does with the game in the future!
