Playing marathon sessions tends to ruin a game for me. I play 8 hours every night, then a few nights in I get burned out and stop playing altogether. I find it's best when I limit myself to a few hours a day - then the desire to play stays and I get more overall enjoyment out of it.

Yeah I couldn't do that many hours! (another serious answer)
I want to savour every moment, so would only be able to do a few at a time in order to stay comfortable!
