I found a small trivial way to gain interest but it wasn't normal. A few friends of mine had the same mind set and said, what do i do.. (i expected better from them.. lol) so i tried an experiement. I dropped in my level system and made the requirements to level up really really hard as to also expand on a goal system. Then they played. Didn't hurt the over all balance since its so hard to gain anything from it but being something tangible to reach for, i think helps the newer group of gamers.
