lol.... i dont have time for double tick worlds any more.
Now that school and work are back in full-swing, this is my daily schedule:
Wake up, get on BD while i prepare to leave (1 hour)
Go to first class (2.5 hours, including driving)
Get on BD for 10 seconds to make sure nothing has happened
Go to second class (1.5-2 hrs)
Get on BD for 10 seconds to make sure nothing blew up
Go to work (5-7 hours)
Go home (1 hour)
Sit at home and play BD, while attempting to do homework, watch TV, and talk to the hordes of people who spam me on MSN. (3-4 hours)
By this time, it is around 1 AM, and i have to get up for school at 7 AM...so i sleep for around 6 hours.
This was compared to my old schedule, where i had no work through school

and i could be on every tick until i slept (which was only about 6 hours).
single tick worlds are the only way for me.
