Monthly payment blows for several reasons.
-Not all have credit cards - or their parents won't let them use it
-Not all have paypal - or trust it
-What if you get bored in the middle of the payment?
-It costs much, MUCH more to keep it up instead of buying it once.
-The economy sucks as someone said earlier so it's really unnecessary to add to your tax bill.
Yeah. 1 time pay ftw. With monthly pay they'll earn just as much money because not as many people will be playing it.
