Released in 1992, before even Wolfenstein 3D, this was one of the first games using a 3D environment, a real landmark in gaming and certainly RPGs. Plays very nicely on Steam Deck via Heroic launcher after some button remapping. Game controls are fairly horrible, inventory management painful, graphics &sound very dated (monsters and npcs are sprites!). Gameplay... classic 90s style maze like maps, find items, traps, fight monsters, lots of repetition & backtracking through levels. You definitely need to use walkthroughs as the levels are huge and often important items/locations/info virtually impossible to locate. And it goes on way, way too long. However it is still a good game with lots of charm, and you can tell the devs had a blast making it.
