I have been playing D&D for almost 30 years. But nowadays I find myself disliking D&D more and more. By this I mean D&D rules and mechanics. 3.5e of D&D is the best D&D edition for me, and I don't much care for 5e. I also am very much NOT a fan of the D:OS games and found them to be terrible games. So I am here purely as a huge fan of the original BG video games and especially as a diehard fan of the Forgotten Realms setting, which is my favorite fantasy setting by far. I am passionately into FR lore and have almost all the 3.5e FR source books and almost all FR novels.
As for recent cRPG games, I love the PoE games and P:Km. These are awesome games and the true heirs to the old classic RPGs. And for the record, P:Km sold very well, well over 1 million. I also love the Dragon Age games and consider them to be part of the cRPG genre.
I got burned out on 3.X when I learned about the Ivory Tower game design (where they made some player options deliberately stronger or weaker on the idea that a player would learn from their mistakes and not play that option again...nevermind that it screwed over some concepts).
5e is the best D&D so far, lots of narrative flexibility in character design, though some classes are still way to cookie cutter for me so I can only do limited build plans and level-up/XP spending is sort of how I engage between sessions and help frame my characters state of mind and intentions going forward...so...when you have like a cleric, where the only build choice points are at 4th, 8th, 12th, 16th, 19th...where you get the option of Feats....it makes it a bit hard to get as good a hold on my character's plans and make them unique and individual as I can with a system like City of Mist where character advancement is more ongoing and related to events in the character's life.
3.X had a lot more building in it, but with the Ivory Tower design where some options were deliberately weakened.....I can't trust it so...I lost taste for it.
but my favorite games tend toward City of Mist, Monster of the Week, Hero System, Scion 2e, Legend of the Five Rings 5e, Star Wars FFG/Genesys, Fate (with some heavy houserules...I love Aspects and the central gameplay mechanics, but the Skill pyramid thing that many versions of Fate use is annoying)
