Alternate Versions and Ports.
Commodore 64 (Original)
The original and best. Myth still looks pretty good on the ancient 8bit hardware. Later followed by a cartridge version for the ill-fated C64gs. Dont forget to type in: "SYS 3 MYTH" (with the spaces) on the black screen to boot the cart. Lemon64 linkage.
Here's a set of C64 longplays on YouTube: part 1/3, part 2/3, part 3/3.
ZX Spectrum
Similar but different to the C64 level layout with a few unfamiliar locations like the one below (right).
Amstrad CPC
I can't find much on this version. It looks very similar to the ZX version (no suprise).
NES
Renamed "Conan the Cimmerian."
Note the player sprite is now more Conan, less average schmuck in a vinyl vest.
I guess the Nintendo crowd needed a familiar licence to give the game some cred'.
The gameplay (at least on level 1) is simplified and faster-paced which isn't necessarily an improvement. The music is lousy, silence is golden sometimes.
Amiga
Similar to the C64 original with lush 16bit visuals and some gameplay tweaks making it a bit easier. The harpies are a lot less annoying and it's easier to take out Medusa with her more predictable attack cycle, player control also seems a bit more responsive and fluid compared to the C64's slightly ponderous control response. The graphics are easy on the eye too. I place this version a close second behind the C64 classic which wins out because of the nicer intro sequence and the impression the 8bit hardware is being pushed harder. The hero character has had a complete rethink too now he's a wild haired barbarian type. see: artwork for more about this.
Amiga CD32
Identical to the previous Amiga version. Like many CD32 titles, not much is new over the standard Amiga version which is a shame because some AGA love would've made a great game even better.
A good game if you hadn't played it already on your Amiga 500.
Atari ST
This game was never finished. As with many ST ports it bares a remarkable resemblance to the Amiga version. Note the little graphical tweaks and colour downgrade in the stats bar.
Remake
In development, fingers crossed it'll make release. See the teaser video (youtube).
