honestly i dont think that playing a different game could help because one time when i tried to quite i started playing wc3 and i got hooked on it and played it all the time and it was more time consuming for me because i liked to play team games and they usually lasted anywere from 30mins to over 2hours.(the two hour games were either playing hide the farm or looking for the hidden farm. i am kind of pissed off that you cant do that anymore.) but eventually i did come back to diablo because i realized that diablo is a game i can play for as short or long as i want to in wc3 and most other RTS games if you leave before a match is over you get a loss.
Think not disdainfully of death, but look on it with favor; for even death is one of the things that Nature wills.
Maybe it's better to not play these games so much. Then you won't get addicted and won't have so many problems with money, relationships, etc. Remember, video games ruin people's lives...
