Galahad pretty much summed up the attitude of the time unfortunately-as was almost inevitable,the more original games tended to be the superior games.
Although, Graftgold showed exactly what could be done with Coin-op translations when done properly with Rainbow Islands.
Likewise Ocean France with Pang-whether that was the case with the unreleased Snow Bros.,who knows?
Always regarded it a pity that although the ST-portitis was inevitable, that Ghouls'n'Ghosts couldn't have been done a tad better-with the exception of the music that game was utter cack.
I was going to say that the cutesy-style simplistic style game seem to produce the best translations, but the odd conversion like Operation Thunderbolt translated across well enough too.
