2 player games?

2 player games?

I'm looking for games for only 2 people, & not board games. I'm putting together a binder full of game rules, along with the equipment needed to play them for when I'm camping with my fiance, & I'm having troubles finding new games I've gone through This site & found a few, but I'm still looking Card games, scavenger hunt lists, talking-type games, & drawing games are all good. I would especially like to hear about games that you've made up yourself, or ones that aren't very wide-spread.
