Not true. The X68K was very good for arcade ports and console-style games, but the Amiga was far more flexible, as evidenced by the fact that demo coders are still pulling new effects out of it. You never could've done Desert Dream on the X68K, for instance.
And yeah, the price would've been a problem too. For $3000 in the late 80s/early 90s you could buy a fully loaded 486 and play the hell out of DOOM, which the X68k couldn't do.
