There's a couple reasons, I think...
There seems to be an idea draught, myself included (as CD for this forum). We've played a lot of the games...I try all the time to think of new ones...but it gets harder.
Plus, there's not even enough activity going on lately to really keep anything up. When you have three people playing, it's just not as fun.
If you have any ideas, George, please, do go ahead...I'll welcome it with open arms.
