How has no one recommended Dungeons and Dragons: Tower of Doom and Shadow Over Mystara? Classic Capcom beat 'em ups with a ridiculous level of D&D added on top.
Cast a spell at the Beholder? Bad idea, unless it's looking the other way. Dwarves find extra treasure, there are tons of secrets and hidden items, the cleric can turn undead, it's a ton of fun. Available via emulation or as a 2-pack on Steam.
