Good RPG/Open world games?

Drakensang is very good, a bit slow tempo but the story and world are nice.

Your kidding right! X-2 is nowhere near as good, granted there are better FF's

Got it, played for tons of hours, sold it, end of story.

+1 for KOTOR

dito

New Vegas FTW

Dark Souls was released almost a year ago. He obviously wasn't talking about the PC version...

You should try Risen 1 if you are looking for a great combat system. Controls in Gothic it wasn't a problem for me. Did you try the alternative controls config? Many recommend not using the default one.

It's open world?

Totally seconding this. This is one of the games that got me into open-world RPGs.

You appear to be a fan of 3rd and 1st person shooters.

So judging by that here's a list of PC games ranging pretty widely in the RPG genre (and some that are just shooters which are more varied than most).

Games You’d Likely Enjoy:

The Elder Scrolls Morrowind, Oblivion, and Skyrim
-Reason: They’re all basically Fallout 3/New Vegas in a fantasy setting. However, that might be a turn off because it’s more of the same. Morrowind is the most different of the three since it uses a system where blows can miss when you’re within connect distance. This may be a deal breaker for you.
-Availability: Steam and other retailers.

Red Faction: Guerilla
-Reason: 3rd person shooter rather open ended with small RPG elements. Run around destroying buildings and causing chaos if it pleases you.
-Availability: Steam and others, but requires GFWL.

Borderlands
-Reason: First person shooter with a Diablo-esque weapon acquisition system. Story is kind of Lost-esque (lots of vague mystery with little pay-off), but the characters are enjoyable and the game is fun enough alone, but pretty damn fun with friends. Area progression is rather linear, but each spot has a few relatively basic sidequests involved.
-Availability: Steam and others, online uses Gamespy IIRC.

Games You’d Likely Enjoy, but Are Outside Your Usual Fare:

Mount & Blade: Warband
-Reason: The game really has no plot or purpose. You start as a lone man and try and make a name for yourself in Calradia. You recruit men, fight bandits, level up, do (highly lacking in variety) quests, and either join a faction or form your own kingdom. The combat in this game is completely unforgiving, but is it ever rewarding. Not to mention fighting battles of 150+ men on each side and trying to stay alive in the melee. Very active modding community and it has THE most intense multiplayer ever. You will get OWNED when you first start the multiplayer, but once you learn and you start getting into duels that last over a minute nothing matches that feeling of elation when you finally best an opponent who used to kick your ass.
-Availability: Steam, GamersGate and others (or support the devs more directly and buy it on their site)

Games You Might Enjoy And Would Expand Your Horizons:

Neverwinter Nights 2
-Reason: While you can’t go anywhere, there’s plenty of sidequests to do. You can treat the game more like a Diablo-esque game and rely on your companions’ AI to perform adequately or treat it more like a strategy game and take control of everyone. Be forewarned, D&D 3.5 can be an unforgiving bitch to learn so use builds you find on fansites. Also, when the main adventure, 2 expansions, and premium module are defeated you can load up modules from the community. Hundreds of great adventures are available.
-Availability: Due to rights disputes it appears to no longer be available for download. However, NWN is available on gog.com, but it’s an uglier game, although it may be easier to learn since it lacks the large party to control.

Baldur’s Gate 2
-Reason: It’s much like NWN2, although it uses an older version of D&D which is arguably easier to learn (other than THAC0). At the very least leveling up won’t take you hours of research to get it just right. Amazing story, amazing characters, but somewhat linear. There’s plenty of quests to distract yourself with, but there’s only so many quests in the game. Difficulty can be adjusted at any time while playing the game. And I know you’re asking, why not Baldur’s Gate 1? Well, BG1 the story is weaker, but the big reason is AD&D at level 1 is a giant pain in the ass. You are completely at the mercy of the die rolls. At least in BG2 you start around level 8 which gives you lots of tools to work with. Level 1 wizard in BG? One damn spell each day.
-Availability: GOG.com right now, and around Christmas/Spring an enhanced version of the game will be available from Beamdog for the iPad for $10 or for PC for $20.

Dark Messiah of Might and Magic
-Reason: Completely linear story, no sidequests. However, the combat is fun, WAY better than anything in the Elder Scrolls. You will cackle with glee as you kick a barrel down a ramp and send a poor goblin flying into a fire. Biggest downside is the multiplayer is dead in the U.S. and the terrible inventory of Arx Fatalis was carried over.
-Availability: Steam.

Risen
-Reason: You could try it for free using Gamersgate’s VOID. Combat early on is all about timing, but it’s a relatively fun game. I’m only a few hours in, so can’t tell ya much.
-Availability: Steam and others.

Star Wars - Knights of the Old Republic
-Reason: It’s basically Star Wars + a D&D-esque system.
-Availability: Steam, although may be bundled with KOTOR2 online soon.

Games Way Outside Your Preference, but Hey, You May Like ‘Em!

Might and Magic 1-6
-Reason: Well, it’s 6 games. Although 1-5 are the same tile-based first person dungeon crawlers in design, M&M 6, however, can be treated more like a modern first person game (with a little help from some tools you can find on the internet). What do these games bring? Hours upon hours of questing and exploration with stories I honestly wasn’t too good at paying attention to at the age of 4. Worth a look on YouTube at least.
-Availability: GOG.com for $10 for all 6

Star Wars – Jedi Knight II and Jedi Academy
-Reason: First person shooters with 3rd person lightsaber swordplay. Jedi Knight II story is linear, but Jedi Academy gives you some choice in where you go. Fun games, but the lightsaber kind of makes most of your other weapons useless. Vaguely RPG-like due to the force powers.
-Availability: Steam
