I played Dune 2 on the Amiga after seeing it
on my friend's PC...I actually thought that
the PC version had better graphics (VGA compared
to OCS?), and I think it had speech through
the 16bit sound card which the Amiga
didn't have. It was an excellent Amiga
game though...kept me up many nights. The
only thing I didn't like was the inability
to select more than one unit at once...and I
didn't have a HD so it was all - about swapping
disks.
That same friend also had Doom on his 386...I
recall it as being very fun and playable, but
that was long ago I can't fully remember.
