I know satisfying customers with a reasonable payment system for any of your services is of the lowest priority right now Square-Enix.. but it would bode well for you if you would make attempts to be taken seriously about looking into alternate payment systems, and a dev tag dedicated to that purpose would go a long way in that regard.
The FFXIV boards, where players aren't even required to pay, are showing frustration spillover about the current payment systems. The FFXI boards are up in arms over it, armed with pitchforks and ready to march on headquarters. I REALLYYYYYY think it would be wise to start responding..
