I loved playing FFXI and to be honest, I really never got much from the FFXI website. There was the live camera which was pretty neat,,, if you were really boared, but that was about it as far as what was going on in the world live.
Right now we have a pretty usuable website, ffxiah.com to find out what is going on in the AH, but I have always been a little leary hearing about viruses and attempts to get your password from that site. An section on the official site would kept me coming back to it almost daily.
Another MMO out right now has an online armory that you can look at your character (and i belive others) skills, and items they have currently equipped.
I have purchased an app for my iphone (they have free ones now) that shows time of day, and ship schedual and shop openings/closings. I use it often as its alot easier than going to a website or just a quick glance to see if I have time to stop at an AH to sell some stuff and dont want to miss the boat.
I think a beasteary for different smartphones would be huge, I would pay 5 bucks to have it in so I could browse them during the day while I was away from the game.
Maybe a recipe book too.
Anyways, what things outside the games would you guys pay a little bit of your hard earned dough for?
