Yeah they should all work fine, I think it's more personal preference really. I went for a slim mouse as even though it's not as comfortable it keeps the overall size down and I also wanted the hinged keyboard so it was more like a netbook when in use. It also leaves the sides and top edge exposed so you can access all buttons and ports which is something to watch out for when buying generic cases, all tablets are a bit different!
If you're using it as a media device either on it's own or hooked up to a TV then I use a cheap BT flymouse too, it has media buttons and obviously a touchpad and keyboard. Makes watching films, Youtube etc much more comforable! The Ipega pad I have also has a mouse mode and media buttons which is handy.
Is that Need for Speed MW the older one or the one from a couple of years ago? I would be impressed if it was the recent one as I tried to get the Hot Pursuit reboot (2010?) working on my A6 laptop and it was just shy of being playable.
