I would really like to bring some of my game concepts to a larger playtest pool, and doing so online seems a great way to do so. Originally, I'd thought about GatlingEngine or even Vassal, but I never EVER seem to be able to find players on either doing much of anything, aside about six people playing loads of games I've never heard of (Vassal) or sitting there waiting for opponents (Gatling). On top of that neither one of their forums has been useful for getting people to reply (not like here). Basically, I've given up on both unless I can be persuaded otherwise.
I was reading here (and at its site) about Lackey CCG. It seems like a really nice fit for what I'd like to do (I've several card games ready to beta); how have people done using it for their own new games vs. established plug-ins? I was also wondering if anyone here had ever tried out Kongregate.com's flash game generator. I think they call it "Flash Lab" or something like that.
Speaking of using flash, how hard is it to learn?
