Worst luck i've ever had would have to be with WoW. I played the beta, and they allowed you to keep your account after they went live , no characters or anything , but least your name was saved so you could have it.
The account got hacked while i wasn't using it and happened to get an email from blizzard saying they had me starting another 6 months of game cards.. that i didn't buy.
Phoned them up and said i didn't buy anything , spent something like 6 hours total on the phone with them to discover that when i left the whole guild i was in was hacked by one of the members and that my credit card had been charged, which was fixed and then they offered me a free year of game play because of the incident... bad choice to say yes as i did play again.
Funniest worst would be i have owned 6 xbox 360's , 4 of red ringed within 2 months of owning , hence return to where i purchased , 1 has damaged cd's that one microsoft took back along with the 2 games it ruined. And 1 that is currently doing a damn fine job.
Also have had 3 PS3's that have broken, and a Wii that gathered so much dust that when i went to sell it i though it had grown a twin brother on top.
Have had a DS lite that had a hinge crack , a PSP that fell off the 8th story balcony of my apartment , have one side get run over by a car , and still turn on with no damage to the screen and one some minor cracking on the side that got run over.
Also way back in the day when my 5.1 surround sound speakers for my PC had the wire get damaged , i replaced it only to have not realized i didn't use the right amp cord causing half my parents house to go dark.
So having a price tag on FF13.. which if you enjoy repetitive tasks , you'll love this game .. we gave up on story long ago , this time you get to fight twice the bad guys , with half the love. Meh its a price tag, you can remove those easy enough.
