I'll tell u something guys... not a solution though, more of a rule I set for myself.
If u stopped playing one game/vn after playing for consecutive hours/days, (say for 3 days almost without sleep) there are only two reasons:
you never got interested in it(playing/reading for the sake of playing/reading), or
you haven't reached the hook (interesting part/event/climax) of the game.
Most of the time, the former would be your reason. The latter is uncommon, but still it happens.
Let's get to the main thing... the what to do's.
Never start another game/vn unless you finish the one you're currently playing/reading.
If you didn't like the first main event, stop playing it. (seriously) (like = interest... something like this)
For VNs... if you don't like any of the heroines, stop and try to look at reviews to see if there's anything remarkable with the story. If there is, then it is your choice. If not, move on mate.
For games... I prefer playing anything I could go with because I consider everything and anything as training for something. (did u get that?)
I made it so that it would look like as if I was talking to you guys but... I was really talking to myself regarding this^ the rule... thingy... and all... you got it.
One last thing, TRY to close your browser when playing or reading... unless you're keeping watch on the forums or your irc channels... or consulting an online dictionary for translating or... downloading something. (emphasis on TRY, since it' really hard to do for some)
PS. This rule are for average people with average life. Including all the people above, I guess? Extreme hardcore guys should just do everything they want to.
(This is what you guys were talking about right? If I'm wrong then just ignore lol)
