The vast majority of the best games for our beloved system come from the land of the rising sun, but there are still some non-Japanese gems in the heap. However, I'm interested in hearing opinions on the best non-Japanese Turbo games that were original to the Turbo. So for example, Dungeon Master, while a great game, doesn't count because the Turbo version is a port. But a game like Dungeons & Dragons: Order of the Griffon, for example, does count, because it's a console exclusive. So does Darkwing Duck, if that's your thing.
I would start this thread with my own suggestions, but unfortunately (fortunately?) the only games I've so far played in my budding relationship with the Engine were Japanese-developed.
