paul_gadd, even licencing ports costs a lot of money - the more successful the port, the more unlikely we'll see one for the Amiga. Look at Shogo and Heretic2 - good enough games but flops on the PC, so easy to get ported.
Games like that aren't going to make people suddenly sit up and take notice of the A1 or Pegasos. I think you were right when you said they were aimed at Amiga die-hards...because, honestly, its unrealistic to aim them at anything else.
