If anyone out there plays Magic: The Gathering, I recommend checking out the Forge game at CCG HQ. It’s a great system with a bunch of very dedicated developers and a large body of motivated testers (players). It’s very much a system in development, but there are new beta builds out every few weeks and I’ve been quite impressed with the effort and the results.
They currently have 9855 cards available in the game. The very active community finds bugs and problems (there are plenty) and they are usually addressed very quickly. The number of new cards, bug fixes, and new features rolled out every few weeks with each new build is impressive.
The latest beta build came out today. I haven’t actually played it for quite a while, but I’ll be downloading the latest and giving it a try over the weekend.
