Despite a limited palate, the variety of textures in EQ had a lot of character. There are a ton of places in M&M that I have yet to visit, but my experience thus far leaves me wanting for a lot more variety and mood. Sitting at a campfire staring in to a literal black void for hours on end while mobs are deposited every 45 seconds is gay as fuck. At least give me something cool to look at while we grind.
A big part of why some of the zones/dungeons were so popular in EQ had a lot to do with their feel and, of course, great loot.
