*sigh* Pundit isn't wrong about the whys, but vidya gaems have been under attack from the SJWs and their media for far too long now. Also, IMHO, THE BEST D&D video game of all time is The Pool Of Radiance from SSI released in 1988 Commodore 64 version (first serious attempt at 1E AD&D rules on the computer).

You've played the ten or so sequels with the same engine and the FRUA fangames?
Late to this...
3 followups.
Pool of Radiance > Azure Bonds > Secret of the Silver Blades > Pools of Darkness.
Then there was a Hilsfar which was its own thing but you could port characters into and out of to gain EXP and items.
After that was the Savage Frontiers series which was separate. 2 games.
Gateway and then Treasures of the Savage Frontiers. Uses a slightly different system.
Then there was the Neverwinter Nights MMO from AOL which uses the same engine as the Pools series.
Then there was the Spelljammer game which used yet another system.
Not to mention the two Eye of the Beholder first person dungeoncrawlers.
SSI Also did games for TSR's Buck Rogers RPG and its pretty good really. And a pair of Dragonlance games. Both use a heavily modified Pools engine. Think they also put out a pretty mediocre sidescroller for Dragonlance called Heroes of the Lance.
If recall right they also did one game for the Thunder Rift setting from Mystara.
SSI for a span was pretty much the go-to for D&D PC games.
Back on topic: And of course they moved on to new targets pretty fast.
