Wasteland 2 is definitely worth buying if you like making choices with many outcomes, a long lasting experience with tons of replayability, and RPG elements. The only reason you wouldn't like Wasteland 2 is if you are looking for a deep combat system, since the one in Wasteland 2 will become repetitive and it doesn't offer much strategy or tactics.
