It's ok if you sit at your PS3 all day but some of us cannot and can lose players for a full sim period or have them playing out of position like your #1 D-Man moved onto your 4th line for the full sim.
and the next thing you have a 50% PK and a bunch of losses.
Alright lets not get into the "some ppl have a life" thing. We all have things to do. Some go to work, some school, and some both. The fact is though the 2 sim periods are probably going to be like 12 hours apart from each other. Unless I'm on vacation, I'm very rarely away from my house for 12 straight hours.
