Sleeping, screwing around, back log, procrastinating, and vegetating.

Gaming has always been time consuming. Sitting down to play is not like sitting down with a remote for hours of drama and suspense. Its different there is this feeling of commitment, to put in a few hours otherwise it seems like nothing is or can be accomplished. Getting just the right balance is also hard. Too few seems unenjoyable too many and its tiring.
Putting off games until there's time, makes a gaming hobby all the more pointless. A backlog of games accumulates in the back of the mind and in squandered piles.
Other times playing too often, make it dull. Playing the same game day to day is completely monotonous and leads to burning out. Just giving up on a game and leaving it to never be played for a while or even forever.

Joining a fighting games club, its expected that these is a bit of technical jargon and a higher level in terms of technique. But 15 hours of straight to understand the underpinnings of each character is something else. At some point a hobby becomes work.
Most people would call themselves a casual gamer picking up a controller for an hour of paly but now that distinction is changing. With the advent of the Wii, family games are quickly chainging and enlarging the demographic of gamers.
Some say its good because it is expanding the media form to a larger audience. Others say it is ruining the market in videogames as it shifts from the few focused games for the hardcore to the dozens of budget games catering to the larger market of casual gamers.
