If you play for hours like that at a time where you can count the four hours out, there may be some other problems besides this going on...
Good thing I don't have that problem. 2 hours is my whole playing time :laugh:
I personally don't think it will do any bad things (since all those who are infected with space madness probably sit glued to the screen "From Dusk 'till Dawn") What it will do though is shorten the gap between RPing.
