Yes. This game invented the whole 3D maze with overhead tactical RPG combat thing, which didn't become popular until SSI's Pool of Radiance, 6 years later. It was a neat idea to put the game engine on the ROM cartridge, then allow game content to be loaded off cassette or disk. It's just a shame TI only ever released two game modules for it before pulling the plug on their games division. I heard someone created some Tunnels of Doom tools and that they're floating around on the internet somewhere, along with some modules fans have made with it.
