On the topic of DnD:
I like it a lot, I want to try being DM this Summer because I think I could make better stories than my DnD friends XD. (I also want to make up crazy-arse dungeons.)
On the topic of video games:
I think a bestiary that updates when you defeat a new enemy type would be great. (it goes with the concept art idea too). There would be a more detailed sketch of the monster and a short description.
