Time Consumption of Tabletop RPGs

One of the biggest barriers to entry in a tabletop RPG is time.

Case in point is yours truly. Right now as I write this I'm waiting for the other players to arrive for our Exalted game (in which I am a player rather then GM). Next week I'm GMing for another group of players for MY exalted game... my schedule for the next few weekends is looking like this:

This week: Playing in an Exalted game
Next week: GMing an Exalted game
Week of the 31st: ... well it's either I go run ANOTHER Exalted game or something else...
Holyweek: No gaming. So far.
2nd week of April: AEGIS Open meet, I run my Gundam SEED demo game there.
3rd week of April: Another possible Exalted game where I GM...
