thx to see my post...now i have a question where can i download FF11 game?need pay to play?

You must buy the game in a store on online, you cannot download it. And yes, you need to pay to play. The price is $12.95 a month (first month is free), plus an additional $1.00 for each extra character you make. I won't go into great detail about payment options, because it can be found in multiple other threads in this forum.
