Puzzler, I checked their privacy policy
here and it's rather vague. Without knowing what kind of cookies they use, I can't say how intrusive it is.
I do not like "Within our company, access to data is secured through a private user ID and password known only to personnel who have a need to know such information to perform their essential job functions. " because it sounds like they know your password. No one should know your password in case you use the same one on other sites.
I also do not like " We may also track other types of information, such as what games users play..." It does not specify if they are games you purchased from them or others.
These could well be non-invasive, just poorly worded. That's the best I can do.
