Don't forget, the really good games now are well over a gb and there are some that are about 2gb. Not to mention the nexus is a developer device so many people put custom roms on it and nandroids are over a gb as well. That adds up quickly.
My phones now have 0 games on them thanks to the nexus 7, and I know you're already aware of usb OTGto get around space issues
Maybe not as handy on a phone though
