Black Isle and BioWare have both made a number of excellent RPG's (Fallout 1 and 2, Baldur's Gate I and II, NWN 1 and 2, Star Wars: Knights of the Old Republic, Planescape Torment, and so on).

Fallout Tactics is a quite challenging game, which I recommend trying even though it doesn't nearly offer the same amount of freedom and storyline depth as Fallout 2. In fact, I would say that you need to have played through Fallout 2 before trying the former. Fallout Tactics has a challenging real-time combat system which relies a lot on planning and formation to win the more difficult battles.
