Thanks, I actually have a long history with roguelikes and tried to write a 7drl myself once (zengarden. you're a monk, and you tend a garden. occasionally you get stuff through the letter box, has a notion of crafting that I took from df. that's it). While many roguelikes are just tweaks of the hack model, the form itself allows a solo dev to focus on gameplay and build something complete. Hence, the genre has stacks of potential for innovation.
