do you have to pay to play

You can also use your credit card to pay your monthly WoW subscription.

Yup it's a cost for server maintanence and such. The easiest way to pay it is to buy "pre-paid" cards at game stores. Around here they cost about 30$ and last for 60 days.

There are different forms of payment. You don't just have to do the monthly fee of $14.99. You can do like the 6month payment which if you divide it by the total months you actually like save $1 a month. You can also do one big yearly payment as well. Otherwise you can go to where video games are sold and buy a game card which is like $29.99 and that will let you play for 60 days. If you buy the game though, there is 1 month free. You can also download it and try it out for 14 days for free. You can't do everything, and can only get up to level 20 with the free trial. However if you go to the store and buy the game, you can turn your free trial into a paid version and continue on where you left off with the free trial.

You get a month free at first but after that first month you gotta pay which ever payment plan you want.

Yes, it's a pay-to-play game with a monthly fee of 14.99.
