Gothic 1 & 2 are vastly different to 3, and highly recommended. Gothic 1 & 2 are tough and very rewarding, fun all the way through in my opinion, and they are also quite different from any other games (apart from Risen) out there. Gothic 3 was a buggy mess on release, but if you only played it without the fan patch [http://www.worldofgothic.com/dl/?go=dlfile&fileid=166], give it another shot. The fan patch turns gothic 3 from horrible to really good.
Gothic 4 is bad. Really bad.
Fallout New Vegas was a huge step up from Fallout 3. Buggier, but with a great setting and atmosphere.
Divine Divinity takes most of the good parts of Diablo, introduces a far better story and setting, and has a far deeper character customization system. This game can be found on GOG.com for $6, so a real steal.
Nox is another game that borrows a bit from Diablo, but it is not at all a Diablo clone. Here you get 3 different characters, with radically different playstyles, and they also get their own storyline to play through, with different levels (they all converge at points, but they are still different enough to warrant 3 playthroughs). Can be found on GOG.com for $6. I must sound like a GOG advertisement both, but truth to be told GOG has a lot of great cheap games.
Vampire the masquerade: Redemption. Bloodlines might be the better vampire game (when fan patched), but Redemption is more of an action hack & slash RPG. Good character customization, a good story line and fun gameplay. Plus: GOG, $6.
Divinity 2: This game lets you turn into a dragon, that should be reason enough to love it. A fun and very lengthy action RPG, get the dragon knight saga (as it contains the expansion, plus a slightly rebalanced campaign and better graphics).
