Owned both at different times. Atari was better in my opinion. Didn't need to load up its o/s unlike amiga which you had to wait for. Windows long before Microsoft. Those were the days.
I spent many an hour (and knackered many a mouse) playing this on the ST back in the day. I also had an Amiga 500, which saw a lot of Kick-Off 2 action.
I couldn't really say which was better; as a kid in the era before Sega, Sony and Ninendo arrived on the scene, the two of them just seemed awesome!
Does anyone else remember Moonstone? One of the goriest games ever, at the time, it was banned in a lot of countries. This of course made it even more exciting to me as a teenage boy.
I was an Amiga boy. Superior graphics, better spec, and FAR superior sound. I gather the Atari ST was more compatible to connect up to synthesisors and various other gubbins, but I didn't give a TOSS about all that.
And Kick Off 2 was just so playable it was absolutely ridiculous.
