I really want DayZ, but I didn't feel the sale price was enough to get me to buy ArmaII right now. I'd rather get much better deals on my other games I bought and wait until next month to get Arma.
Mark my words though; I must play DayZ and the sooner the better. I'm actually surprised they didn't put the sale price down further what with the tremendous interest it's getting. There are likely people like me who opted for better deals, or people on the fence about getting a game just for a mod.
