Dunno, in DB I would say a project of "Interactive Fiction" (IF) ie. text adventures would be much more complex (to code) than, say, a simple platformer. If you look at some of the information around text adventure parsers, it can be very very complex. Not as simple as a IF COM$="look at the sword" THEN...
If I was you I would look at some of the adventure game creators out there. They are designed for text (with some handling graphics) adventures, and some are very good. Basically DB is for 3D games, and IF creators are for what you want, as the take a hell of a lot of the effort out of it (and there is a hell of a lot). Luckily most are free too.
Oh, there's also a yearly compo that looks pretty good, and some decent games can be found.
Cheers
I am 99% probably lying in bed right now... so don't blame me for crappy typing
