My favorite game of all time, as a gamer, is Fallout (1 or 2, doesn't matter).
Tactic's combat wasn't all that bad, though.
I'm a top-tier backer with Wasteland 2 - they have many people of the original team (you should recognize Brian Fargo). Finally after all those years I'm getting my fix!
The funny thing is, even though I adore Fallout (1&2), and have spent many playthroughs exploring every corner and every little bit of dialogue (even going as far as digging the conversation files to look for inaccessible branches - yeah I went that far) of that game, it's not a game I'd find fun to create. As a developer, I don't particularly enjoy the thing - worldbuilding and story are much better experienced than created (some people have a complete opposite view, and I'm glad!)
As a dev, I much prefer Dwarf Fortress.
