Here is an annoyance I can totally agree with, as I have heard many people having issues with their save games.
No big deal if you’re not a sucker for gamer points, but this could pose a problem if you ever need to move the data to a different memory device. Let’s hope Rare takes notice and issues a patch, and that other developers follow suit. [Note: we have not experienced nontransferable game data with any other 360 titles. Have you?]
It should be interesting to see how such problems are solved in the long run as the amount of titles increase.
