I wrote 2 short text adventures last year with AMOS Pro and I'm halfway to finish a third. I feel rather comfortable with AMOS for this task, but in fact any BASIC dialect will do.
There are a handful of PD amiga specific text-adventure writting tools (C.A.G., ADMS) and some commercial soft (Aegis Visionary) among others. Handy if you're not fluent in any native programming lang, but doing it on your own is always a more versatile option.
Spacejest, Battleforce the Adventure Game, Box, are just the first examples I can remember of AMOS written text-advs. I'm currently making a catalogue of Amiga specific Interactive Fiction tools and games for a personnal project of mine. Hope your adventure will be at least mentioned in it some day! 
@Chaoslord
Which is that text-adventure you wrote? Perhaps I've already seen it but didn't know you were the author, or maybe I wasn't aware at all of it. Tell us about it! 
In the future, I'd like to do a tile based game like Hilt, so I figure this will be a good starting point.
Do you have opinion on the different versions of amos (normal, easy, pro) and what to go with?
Thanks for the encouragement!
