I said I was a die hard gamer slut. Playing Rolemaster proves it. The core idea, two die rolls to resolve any action, becomes insanely complicated in this game. Early on, I created spreadsheets just to keep track of all the bookkeeping required for this game. This game, along with Hero System, Chivalry & Sorcery and FGU's Aftermath were the high point of detailed simulation rules. After those titles, the games discovered that they could be more enjoyable with simple rules. The result of the later games was White Wolf's World of Darkness, Star Wars, and Cyberpunk.
These games do have a following, and their adherence to detailed simulation makes their sourcebooks high quality. I just use the material they publish with a different game engine.
