More than 6hr

[DarthRuben]

Playing for only 30 min. is the best way to go for me, but sometimes when I play 2+ hours unintentionally, I go real crazy when I finally get off.

Ehh, killjoy, I honestly don't see a problem with playing six hours a day. As long as you're not doing it on a consistent basis. I will reach 6 hours a day once or twice every couple of weeks though. Sometimes you just get in a really good killing groove and can't possibly find a way to quit.
