Torchlight 1 & 2 came from a tiny studio with a few original Diablo developers who left Blizzard. Mod support exists (uncertain for Torchlight 1, solid for Torchlight 2), it's a lot of fun and affordable. Dragon Age: Origins is an excellent solo RPG experience as well.
I've been enjoying Victor Vran a lot. It's quite solid too. You might also want to check out Fallout 3, 4, or New Vegas.
Consider the Sacred collection. Neverwinter Nights isn't available on Steam, so you'll need GOG. Skyrim is included, but the older Elder Scroll titles are still worth checking out. Morrowind remains strong, though it might seem a bit outdated now. The Witcher series is another option to explore.
