Ugh, I hate how accurate this is.
My current situation, my friends and I have been playing for about 4 years now. Friend #1 I introduced to poker, Friend #2 was a revival for her, and the other sort of core player is my son that has started playing last couple of years.
We started with little turbo tournaments, but at some point I made the change to a 5c/10c game and it immediately took off. We have our wives + a few other friends who could jump in. Increased stakes, added mixed games at times, etc.
Recently it has felt like it is dying. Friend #1 wins every time, I'm usually next in earnings, occasionally my son has a big night. Friend #2 punts, and has dusted some stacks at other games nearby or casino. No one else can really keep with us and don't take it seriously enough to improve. So no one wants to join, Friend #2 is discouraged, and lately I'm the only one wanting to play. Really sucks because I enjoy it as a friend get together and far more casual. Plenty of games in town, but I'm not always interested in committing that much cash.
