You said the old community around you just stopped showing up, did they find other games or just quit for the time being?
I find it very hard to get people committed to AoS because for the most part our club just kept playing 8th first and now it's all basically 9th age with only 3 of us playing AoS more or less regularly.
We did a 3v3v3 battle once, and everyone seemed to have fun, but most of us are in our late 30s or early 40s and people just don't want to commit to learning and getting the most of another game, even if it uses the same minis (another club member tried to attract people to KoW, with the same results). Those who left WH for the most part have picked up Xwing or Infinity which are also very time consuming to be up to date to.
This is a small town so I'm pretty much stuck with this group.
Should I keep trying?
