I suppose this is as good a place as any to mention that Dungeon Master and its many clones have the absolute worst combat UI in existence. I mean, having to click on each weapon hand individually after it becomes unmasked, constantly spinning your mouse in a circle, clicking away at the damn weapons. At least EOB3 had a "attack all" button. These were PC games, though. There is absolutely no reason why each weapon couldn't have been assigned to a key. The way it works, though, it's impossible to even use an external key binder to accomplish this; you'd basically have to hack the game or send absolute position mouse events, assuming the game can even handle them. This interface only becomes worse with spells, where you have to waste time navigating byzantine spell casting interfaces (although at least EOB had a well-organized menu, but still you couldn't cast the same spell twice without effort).

I say all this as someone who actually liked Dungeon Master and EOB, to an extent. It seems the Legend of Grimrock developers wanted to double down on the bad UI, though, and in many ways go back and make things worse. Especially the magic interface.

We need Bloodwych and it`s sequel here!

Legends of Grimrock dev have new game in dev called Druidstone which is out late spring.

The AI is the worst part of this type of game, tile to tile "pick the closest tile to follow the player". The thing I did love most about Dungeon Master was that on my 1084S monitor with my Amiga I could hear faint footsteps10 tiles or so away, getting closer, and your wondering what is going to round that corner and attack. I do prefer Wizardry like turn based combat but Dungeon Master seemed to really immerse you into the dungeon, as a living world to fear. Like what new creature you will run into next and of course unlike Wizardry and Bards Tale you could hear and see the enemy chasing you, and the puzzles were fun and not some illogical crap that gets you stuck in a game (before walkthrooughs on the net were available), In particular Wizardry V and Wizardry VI.

That's 8 current games only available on Steam that should be available here GOG . They are indie retro RPGs so unless they prefer to sell their game exclusively on steam I am not sure what is going on.

I will buy any of these on GOG if possible, but during a search on GOG most of these are not available here yet .

I also have "The Keep" on steam and finished it but I would not recommend it being as generic as possible.
