About 4-6 hours a day on weekdays 6-9 on both saturday and sunday. I'm usually up in the middle of the night and there is nothing to do.
So... anywhere between 32 to 48 hours a week unless something is happening. Embarising really.
It was even more when i was obssessed with MLB Power Pros. I put in like 8+ hours a day. One day I had like.... 15 hours in... I don't even know how that was possible. (Well I do, I had a friend over at like 1 am when we started playing, then played it all day... but still.)
