Play Arcanum. It was made by Tim Cain and co after they left Interplay post Fallout to form their own company TroikaI honestly wish there were more games like the old school Fallout games. Beyond there being Wasteland 2, the only other developer that even bothers to try a isometric post-apocalyptic style was some Russians who literally made their own love letter to Fallout.
Imagine a place of wonder, where magick and technology coexist in an uneasy balance, and an adventurer might just as easily wield a flintlock pistol as a flaming sword. Welcome to the land of Arcanum.
