I just had a look at it and my verdict is:
Yes.
DBP should be useful to create any sort of game, but your limitations come down to your own time, abilities and how many people you've got to work with and their skills & abilities.
In the case of The Sagittarian, it seems to be a fairly simple text adventure and similar to a project I started a while back called Pulse, thread found
here.
It also seems simple enough for a first project. I did put the source code online to explain to somebody the LUA functions I used, so if it'll help, you're welcome to check it out. I'll link to the post as it explains the LUA plugin I used.

The only thing is that my system lacked an inventory, but you're welcome to have a ponder and hopefully you'll find something useful. I don't mind sharing the code.
But I guess I should mention the obvious, you won't be able to export it to flash, just as a stand alone .exe I don't think there's any possible way of getting a DBP game to play through a browser (if that's your intention).
