Wasteland 2 is decent. It sticks a bit too close to archaic gameplay choices, but once I got over the initial difficulty spike I started having a lot of fun. The director's cut edition is really stable & the game has only crashed on me once so far.

Wasteland 3 is a big improvement in terms of graphics and gameplay, but it's still busted and I had to stop playing it because the game crashes constantly. Personally I'd wait a year before playing it.
