Over the past few weeks I've been running Greg Gillespie's Dwarrowdeep for two separate groups, one online and one in-person. The guts of the system we've been employing is Basic Fantasy, precisely because it is so basic that it provides an excellent framework for me to hang a bunch of ideas off. Also because as a Brit of a certain age it reminds me a lot of Kwik Save's No Frills own-brand, which I have nostalgia for in an internalised traumatic way.
