You're getting older unfortunately. I've been watching this happen among my friends for a long while now. They all slowly grow up and leave gaming behind replacing it with other hobbies or interests. Your free time becomes more limited the older you get and the more responsibilities you aquire in life (career, spouse, children, etc.). I'm one of the last hold outs from my childhood friend group, and even I'm slowly starting to lose interest in gaming. I don't think I'll ever give it up entirely, but it definitely doesn't hold the same appeal for me that it once had.
