Welcome to Android Forums, Laurie.
The tablet you have in mind has some pretty low specs. I don't know how well it will do the whole games thing. Kind of a get what you pay for situation there.
I haven't played any games at MSN.com, but I assume they are flash...so probably no. However, the Google Play Store has no shortage of games, both free and paid, for you to try. Odds are there are some pretty close duplicates of what you play on MSN.
By windows email, are you referring to the built-in app in Windows 8? Or are you thinking of Outlook? They do have an app you can download to access your outlook email.
If you're referring to a corporate email account through your work, there is also support for that. I am connected to my work's exchange server.
I'm not entirely sure what you mean by your last question. I can say that it will not have any cellular radios, so you can only connect via wifi.
