Day 18 — Favourite Game System
d20. Not to say that the d20 System and D&D 3rd Edition are the best game systems ever, because I definitely don’t think that’s true. (I don’t even think 3rd Edition is the best D&D; that nod goes to 5e, in my opinion.) But the underlying paradigms of d20 — especially including the OGL and the idea of truly open gaming— completely reinvented the idea of what D&D was and could be, and pushed the potential for gaming as a narrative platform into new realms.
