Mnemon: Sure, of course. And I backed a few, too - and think it's great they are around and happen. But my 'dream' project is something that'd surprise me and gives fresh impetus to the gaming industry. I've started out in pre-PC times; the same (or similar) gameplay, narrative structures, themes, topics etc. do become old.
Yeah, but, no, but... Sorry, a Little Britain fan ;-)
In my view a given framework that is plot focused -let us say, e.g. "high fantasy RPG" - could have indefinite richness if there was enough good, creative, even unconventional writing about.
Rarely are the games particularly well written, so that the lore and the weight of the gameworld pull you in, and one also comes to delight in or hate party members and NPCs; or to care about the plot-line and story choices.
If one is a Discword fan, this could be used as a literary example.
I am sure individual books vary in appreciation per individual tastes, but there are now 40, and I think many more would be desired, if possible. The lore and attachment has only become deeper and richer thanks to successive build-on on the original idea.
