Factory reset - ICS update help

[elliotclem1]

Hi,
Updated to ICS via Kies from Gingerbread a while back now, however since I didn't do a factory reset before updating many applications freeze and crash.
I'm currently in the process of backing up my phone before I do a factory reset and do a clean install of ICS.
However I want to make sure that I don't loose any game saves after restoring my kies backup. So my question is does Kies back up game saves along with my texts, numbers etc? And if not how can I back game saves up.

Many thanks Elliot

I wouldn't trust Kies to back up any app data. I suggest you copy all your games and data folders to your SD card.
