Unfortunately, no. The nano games are only compatible for those with the scroll wheel. But dude, trust me. WIth the app store, you won't be disappointed. Some apps are free and some cost money. Some apps are really nice.
Here are some of my personal favorites:
-Tap Tap Revenge
Some of these cost some money, others don't.
Trust me. I wouldn't worry about adding ipod nano games to your ipod touch.
PS: If you do happen to get your ipod touch, I have a full blog: www.ipodhow2.wordpress.com
It tell you how to work with your ipod and if you really want to push it beyond it's limits, jailbreaking or hacking.
