IMHO, In a perfect world, OMNI Posts should count. But like with reputation, it is being abused by a few members. They are using what was once a few, and has now has become a lot of silly contentless games as a vehicle to get to "Evangelist" or "Legend" "status".

I'd support one of three things:

1. OMNI Posts no longer count (easiest)
2. Delete the game threads on a periodic basis. When the posts are deleted, the counts go with them.
3. Get rid of the titles (Evangelist, Legend).
