As discussed elsewhere, it's an incredibly complex game. But is it unnecessarily complex?
I've made this topic in an attempt to determine what could be cut from ADOM without significant loss of what makes the game so special, if anything could be, or should be, cut.
My own thoughts:
The Minotaur Maze, The Old Barbarian, The Assassin Prince, the Animated Forest, and 10 or so levels of the CoC. The Quickling Tree.
I usually skip the Maze and the Forest, and the Prince and Barbarian are ignored until strictly necessary. The CoC goes on just a touch too long. The Quickling Tree seems nothing more than a too-easy way to gain speed.
The Rift, I'm undecided on. I like having the option there, even if I don't often use it.
What are other peoples' thoughts?
