The hobby goes up and down. But overall, it's still a blast. Some of the best times are battling with a buddy all afternoon on a classic game.
Just last week in Classic League I got paired up with 3 great guys, and we all had a blast from the first game. It was just laughing and fun competition.
This afternoon I worked on a game I've been scratching my head on trying to make work right... And I finally found the problem. Then I played 20 games on it in pure joy that it finally worked.
If you need a break from the hobby, take it. Wrap up your games and take some time. People either come back from that, or end up selling everything and picking up a different hobby. It's ok either way.
