26th) Which RPG provides the most useful resources?
Quite a wide open question this. What should be defined as a resource? You could go the splat book approach in which case I would have to say Legend of the Five Rings and Corporation. For both of those games the extra books really expand upon the settings and provide (generally) useful additions to the rules. They’re also both systems where I really enjoy the style of writing so having extra books doesn’t feel like a chore to read through.
There’s also resources in terms of referenced information, such as depth indexes and system documents. In that case I’d have to go with FATE as both the core book and the SRD are thorough and easily accessible. Really handy when you need to look up something on the fly. The community for FATE is also really engaging and including Fred Hicks regularly engages with the games audience including commenting on blogs such as this one (See this post from when I was struggling with some parts of the game).
Finally there’s resources in terms of extras that add to the game without being necessary. Spell cards, custom dice, details character sheets etc. D&D and Pathfinder are the obvious answers for those games but they’re the big publishers, they rely on those sort of extras to entice players to keep spending. It’s even seen in the scale of their organised play, a great resource but not something that the smaller publishers could ever really contemplate.
