Well yeah once gaming interferes with your work, relationships, and life in general it's overboard, but I think 95%+ of people here maintain a good balance and do gaming as a hobby/competitive thing to do off-time.
What is the exact difference between gaming all day and playing soccer all day? One is seen as "demonic" or a "waste of time" by ignorant/misguided people and the other is seen as a fun, socially acceptable way to spend a Saturday. The only difference is perception by others.
