I want to play an RPG!!!!

Last I checked, the Elder Scrolls games were classified as RPGs! I personally like all of them, including Arena and Daggerfall! But I recommend Skyrim or Oblivion......Morrowind is great but the combat system can be quite rage-inducing for some!

Error 53. Best almost-RPG game in the business.

I don't know why but every time such threads arise people seem to forget Underrail. It is a RPG with a semi-futuristic kind of post-apocalyptic setting (with isometric view and turn-based combat). You only play one character but you have to pay attention on what skills to raise and you should decide before hand how you wanna play otherwise you could get stuck or have a hard time. Although I heard the game shall be a bit easier at the start after the latest patch.
Which brings us to the point people might get scared of. It is Early Access. But, in my opinion, the developes is doing a great job. The gameplay is fully functional and mainly story parts and areas are missing. I played two different character builds and got up to 40 hours and I haven't touched it for some months, so I still have one major update to play trough. You should easily get atleast 20 hours out of it.

You should edit the title, you want to play Divinity: Original Sin.

Sacred 2 gold. That's all you need.

Go out. How good the story will be is up to you. Graphics and sounds are very realistic but the AI is a little buggy. The only downside is that the end is always the same.
edit:as for the isometric view I bet you can achieve it with a pair of Oculus and a drone.

What you are describing is

Divinity: Original Sin.

Got it the other day. Started to see what it's like in the morning. Skipped two meals and almost had no sleep last night. Now I can't wait to finish breakfast to jump in again. Is 6 pm too late for breakfast? This game will do that to you!

In short: Divine Divinity authors and universe. Turn based combat. 2 main characters (for coop or singleplayer). Crafting. Stealing. Non violent ways to finish some quests. Very violent ways to finish quests. Great magic and special arrows. I'm still in the first town at lvl 7, but would dare compare it to Arcanum, Baldur's Gate and Fallout (not F3 and FNV, but the real Fallout).

If you liked Torchlight try Path of Exile or hell try Diablo 1 and 2 and its expansions.

It's not really an RPG, but try Gnomoria. It's isometric, so you of all people would like it. It's a sandbox survival simulation strategy game with an isometric view. I've played it a lot on friends' accounts, but don't have it myself. I'd say I've put a good 20 hours in on friends' accounts and I am currently ready to buy it. I definitely think you should try it.

Mass Effect

Mass Effect (all of them)
Fallout (all of them)
Planescape Torment (looks like Baldure's gate)
Secret of Mana
Diablo III (more a Hack & slash than a RPG...)
And Divinity Original sin seems to be just... perfect !

If you like Bioware RPGs, you really must try Knights the Old Republic, Mass Effect and Dragon Age Origins.

Fallout 3 or Skyrim, Fallout NV is ok but I prefer the setting in 3.
