I never played the PC version or any other version other than on the A1200, but even without these things that were on the PC, that didnt stop me from finishing it and loving the game all the way from start to finish. GREAT Game !!
Although on a bog standard A1200 it took towards the end of the game about 30 minutes for computer to calculate the moves the Aliens would make. At the start of the game the wait time was something like a few minutes, so i guess there was alot more information for it to play around with the further you got.
Once i got my 030 card though, the turns went from 30 minutes to something like 20 seconds !!!
