Which could have been the Speccy's Half-Life?

[SteveSmith]

Following on from an earlier thread, it got me wondering what game could have made the best Half-Life-style adventure, with a gripping storyline and realtime interaction with NPCs and the environment (as far as the speccy could handle).

I initially thought about JSW; Willy could wake up in the bathroom with no memory (a bit of an adventure cliche) and then go and talk to Maria using speech bubbles, but after that there's not much interaction or adventuring to be had, save for exploration. The same with Knightlore or Alien 8; I think they make great environments, but there's no scope for interaction with any NPCs or mystery.
