On all list about best game for amiga is always UFO, so why not make UFO 2 or real name: X-com Terror from the deep possible to play on Amiga 1200. I don't think even that you will need new processor in Amiga because this game has worked on PC 386.
For your questions X-ray about game Warlock this game exist on Amiga. That is amiga version of C-64 game Druid.
