In my opinion finishing MR without ever retraining characters is tedious, but doable. (I haven't done it myself.) The REAL challenge is finishing the game without ever dying. Somebody attempted it once and gave up pretty much straight away.
How about a "magic-only" game, i.e. use no items except key-like items (such as Proper Authorisation, Pass Gem, Bronze Key etc.) and handle all combat with spells only? Or has that already been done? I forget. It's been too long since I've played MR. When's the sequel coming up?
