Well, that ends up as a lot of data on the server. One of the people behind the casual collective just released his tracker stats that show 100 million plays (loads), which would be 10 terabytes, assuming of course that each load resulted in a store.
We don't have a full time server guy so I'd prefer to stay out of that kind of thing, for now anyway! I think next time we'll just design the game around a strict 100k limitation.
We could, but that ends up being a lot of traffic. We'd expect the average person to save a lot more than once (in Robokill it's automatic), so you're looking at at least 100tb of traffic - a pretty big hassle.
If the game routes through rocksolidarcade.com (which is probably a good idea) to save/load things, traffic ends up being 38 cents a gb - 10 for upstream/downstream at Softlayer, and 18 at S3. I think that's pretty close to being impractical.
I'm going to design the next game around the 100k limitation and explicit saves, so this problem will go away anyway.
I think that's exactly what we'll have to do - design the save files to fit in 100k. This wasn't by design - this was 1 day from release, where we discovered that amazingly enough there's no way to tell if a save was successful or not in Flash, so we couldn't ask people to up their storage only when needed (which should be rarely).
