I hate games that force you to draw maps. It means that the level(s) are:
1- Too complex; or
2- Everything looks the same, no relevant landmarks or something as simple as different wall colors.
I beat M&M3 without maps... while the game is HUGE everything, especially the overworld, feels like a proper environment and dungeons are simple, with decent landmarking and good structure, so even more complex ones with dickish warps are doable. Also you can always use auxiliary spells like automap "wizard's eye", jump, etherealize, teleport, time distortion (teleport to dungeon entrance), and the Interdimensional Transport Box item.
This is very different from something like, for example, Double Dungeons and maybe, to a lesser extent, Order of the Griffon, imo.
