Yeah yeah, I know, I've been saying this for some time now. But the fact of the matter is that I believe that play testing is the most important step in creating a playable game. It's where the rubber hits the road, and it's where you find the flaws in the system, and make those tiny adjustments and improvements that wouldn't be possible without extensive testing.
Now that the magic system is in place, I'm in the process of creating a spell list and a ritual list, although other play testers have found the system quite usable as a "use on the fly" magic system. The underlying mechanics are in place, so the system is usable. That said, I am still going to provide a fairly comprehensive list in order to make the game as easy to play as possible.
I've been having some great success finding players on G+, using Hangouts. In fact, I've created a G+ Community specifically for playing Blood, Sweat & Steel online, using Hangouts. I've even started a subscription with a great app called Roll20, which is a virtual tabletop application created to play tabletop roleplaying games online.
In addition to my own play testing, I have 2 other groups playing Blood, Sweat & Steel as well, and they've both done some really cool things with it to adjust it to their playing tastes. That gives me a lot of confidence that this system will be flexible enough to allow easy modding for different playing styles.
There are plans to create a Kickstarter project for Blood, Sweat & Steel in the next month or so. I will be posting updates for that as well.
