There are times I wish I had a partner with game design. I'm currently working on two different game designs now in my copious amounts of free time; however, I'm discovering that I'm hitting the same road block with both. Right now I'm spinning my wheels trying to come up with stunts/techniques/disciplines/etc.
I think my failing is with the fact that I don't really have a clear vision for what I want the games to "do" - other than be fun and provide a reasonable amount of system robustness and dials to play the sort of games I enjoy playing.
But that's a far cry from "having a vision" that ties everything in together. I'm really thinking at this sort of proto-stage that I just need to brain storm and come up with several examples for each item I wish to focus on, stealing as necessary from other game designs that I've seen and then go "Want to do something that isn't here, let's talk," because, in the end, I'm just one brain and I'm good at adapting, not so much at the raw act of creation.
