Achievements List and How Much Storage?

Further to my questions in the General forum regarding the status of games under development and the API, I've got some more questions about the API itself before I start plotting my game around using it's features.

The Data API states that each line of data can be a thousand character string, and assumedly you request keys while the game is up there on the server. How many keys does each game get allocated? The documentation says that "For each user and game you can store several different key/value pairs on the server", but is this a theoretically unlimited value, or is it judged and assigned on a case-by-case basis? I don't exactly want to start giving a player a customisable house and find they can only furnish something the size of a small cardboard box...

The Achievement API only appears to have a single method - the AwardAchievement() method which sets the achievement on the nonoba servers. /Is a method being planned for a future release that gets the current states of all achievements in that game?/ It would be nice to link up the previous example house's trophy cabinet with the Achievement states (and technically a workaroud would be making another set of keys in the Data API that stores this information for me, but again, this would only work if I could assign an awful lot of keys).

Right now you can have an unlimited amount of keys on a user, and we won't lock it down, but rather handle abuse by deleting games that does so.

Regarding API methods, we will open op for getting data about the users Achivements and scores as well.

Cheers Chris. Thanks for the responses here and in my other thread.
Great project you're running here.

What would qualify as abuse? Obviously a game designed specifically to fill up your tables with junk, but what about games using the Data API to store world states for each user?

Morphix - As long as its game related and is a service to the users we are pretty happy about it.

I have a hard time thinking up an abuse edge case. So if its game related you should be pretty safe. Saving of worldstate pr user is exactly what the system is there for.
