Yeah, I would not call King's Bounty Disgaea like at all..
I do love me some Disgaea too. And I feel like its a giant missed opportunity to not have it and games like it, on the PC. I feel like they would be natural fits.
Dofus.
DOFUS, the strategic MMORPG
The Wakfu MMO. Uses turned based grids for gameplay.
I remember an indie game with turned based play, I was trying to get the name for. Did not find it. But, did come up with another Tactics game I dont think I had even heard of before.
Record of Agarest War. Seems there is a whole series of this on Steam.
Agarest: generations of war 45/100 metacritic. ouch.
Agarest:generations of war zero. (prequel.)
Agarest: generations of war 2. Screenshots in steam make this one look like Valk Profile combat. user reviews on these are better then the metacritic.
"Grotesque Tactics" came up on "more like this" looks like it has tile combat too. 65/100 meta. "mixed reviews"
"Rime Berta" also did. Appears to be an indie tactics/Disgaea clone. Very low budget looking. Reviews suggest very watered down in your standard indie way. Also, android game.
So I can't actually comment on the quality of those games. just listing ones that came up.
