It seems a bit odd to me that two of these game systems (One Roll and MasterCraft) are fairly crunchy systems, given my general preference for story-focused games. But they both have an elegant, streamlined mechanic that I appreciate, and the flexibility to make (and to model with in-game rules) a mind-boggling variety of characters. There's a sweet-spot for me where the rules still provide structure to support my character ideas, but also provide enough flexibility to let me make almost anything I want. All three of these games hit that sweet spot exactly.
And I love the toolkit feel of both Wild Talents and FantasyCraft. I am always more interested in tools that help me make the game my own.
And Fate 3.0 (in all its variations) is almost a perfect game in my mind. I was thinking of developing a game that had many of the same beats, and I've largely lost my motivation. Fate 3.0 handles almost everything I wanted, and often handles it in a more-elegant way than I would have.
Anyway, if you haven't checked out these games, please do. They are well worth your time.
