KrazyKain: sadly a good sequal would fail.. why a good sequal? well a bad sequal wouldnt be anything like the original but would adhere to todays rules of a 'good' rpg and might be an elder scrolls oblivion clone, and will be popular (potentially), and possibly even a good game, but not in terms of a true sequal to Stonekeep.
But a GOOD sequal, one that WE want would keep the same gameplay, maybe enhance graphics but the essential gameplay would remain untouched... this would not appeal to the mainstream as classic and oldschool is hated upon by todays immature gaming community.
games like Legends of Grimrock prove that wrong. Things are changing, and there are indie devs out there. Of course it could never be mainstream on the level of say diablo 3 but still...
BTW the original Stonekeep itself had a funny history of a game that was almost shelved and nobody believed it would see tha light of day.
