I've played a few of these. Not a totally huge number, though.
Not counting things like Diablo and the like, I got my start in the genre with Neverwinter Nights series, which I rather enjoyed, and then to the Knights of the OId Republic series which I was also fairly fond of. More recently, I was a fan of the original Mass Effect trilogy (Andromeda be damned), and found Pillars of Eternity to be a fun romp - though I didn't actually finish the game due to, in my opinion, spectacularly poor pacing. It's a testament to all the things the game does right that I look back on it fondly, despite this.
I've never really been a fan of Bethesda games. I've tried every single modern Elder Scrolls game at one point or another, but have never really been able to get into them... the modern Fallout games as well just aren't my cup of tea. Similarly, I must confess to never having been a fan of old school Western RPGs like the original Fallout games, Baulder's Gate, Icewind Dale, etc... to be frank and shallow, they just aren't pretty enough.
Other than that... hrm... I played Dungeon Siege for a little while, before figuring out that it was a fairly bad game.
Currently I'm looking forward to the Pillars of Eternity follow-up, getting around to playing Tyranny, and ... actually, I think that's about it. I'd be all over a new Vampire: The Masquerade game, but that seems like a very, very long shot at this point.
You spend more time modding that game than you do playing it. Jesus.
