I have a foldable recumbent bike in my living room. I picked this because it allows me to be relatively lazy and do other stuff while I'm getting my cardio in. However, I've found that trying to play any sort of FPS makes both my gameplay and my pedaling speed suffer (and that's just in campaign- don't even get me started on what it does to my multiplayer).
I have decent experiences with tower defense games (current favorite is Pokemon Tower Defense- http://www.newgrounds.com/portal/view/566150) and crosswords, but they don't involve much interaction.
Anyone having good experiences playing games while working out, in situations where the game itself is not your workout? What do you do? What do you play?
Things that are not good to play while biking:
Fallout: New Vegas (I don't know why I thought this would be different)
Portal 2 coop
CoD: BO (worst)
