Thanks to everyone who put this together, it's a considerable achievement. Now, for what's wrong ...
I'm surprised not to see the Katauri King's Bounty games somewhere on this list (Crossworlds does pop up at #221 on the extended list in a 58-way tie for last place). I thought my enjoyment of these titles was not particularly unusual. I can only guess codexers toss KB in the same box with HOMM, which makes them city builders, even though you can't do any city building in King's Bounty, just rpg-type things ... hmm.
Also surprised to not see Nantucket place at least somewhere on the list. Probably my favorite whaling card-based rpg of all time, it's always a pleasure to see my entire crew wiped by newborn narwhals.
And, no matter how much anyone tries to convince me otherwise, The (original) Sims is an rpg, and a damn good one. Quite tricky to get to the top of any career and stay there for any length of time. I guess the sequels completely wiped our collective memory of what an odd little gem the original was.
A bunch of games I haven't got around to that didn't make their way higher than Oblivion:
Darkest Dungeon (made it to rank 108 in the full list)
Ghost of a Tale (186)
any Styx games
any Bard's Tale games (221)
any Banner Saga games (221)
Deep Sky Derelicts
Mutant Year Zero
StarCrawlers
