I recently completed M1A1 v1.6 for the first time and although I was very impressed I couldn't help noticing that several things were different to how I had read that they were in the original Marathon.
I had read that you could only use 1 fist in the original Marathon but in M1A1 you could use 2. I had also read that in the original Marathon the Drinniols only appeared on The Rose however in M1A1 they also appeared in Blaspheme Quarantine, No Artificial Colours and Ingue Ferroque. Also on Ingue Forroque in the room with the secret bungie terminal all of the BOBs seemed to be incredibly small. Are these things all changes from the original Marathon? If so does anyone know why they were changed?
