I have fond memories of it too. Granted, those memories involved being utterly confused as to how to proceed, but also being utterly astonished by the graphics. I distinctly remember it being basically photorealistic to my 9 year old self— going back to play it with an emulator was a bit of a shock (and letdown) compared to my memories of it.
I did beat it as an adult. As a kid I may lot have been able to get anywhere, but it was magical all the same.
Accept nothing they offer you without cause. But if you do them a kindness, without thought of recompense, and they offer a gift in return regardless, then it is generally safe and likely beneficial. Generally— exceptions do apply, particularly in the case of user error or suddenly getting really greedy with the gift.
Errr… this applies to the fae, but not customers, I guess. Perhaps the analogy is not perfect then.
