It's funny, I wanted to say that jobtestprep don't offer an ATC simulation game practice, but I just received an email from them that they just uploaded a new beta version of the ATC simulator. It looks very raw, but it works pretty well.

This is for the old version, the AT-SAT, not the AT-SA.
I recommend practicing here also. There is some guidance for the personality tests, even though some think it's something you can't prepare to, and the verbal and logical parts are excellent.
