Going to a tail gate party for a big football game comes to mind,traveling to a fun city and hanging out w/friends for the weekend,going to the movies,snow skiing,water skiing,to name a few.
This assumes that you're talking about our favorite video games. If we're forced to play video games that we don't like, then the answer for me is playing my drums, bass, or guitar! Sex would be more fun in most cases but it's not so much fun giving myself a hand job. Once I find a girlfriend, my answer will be sex unless she wants to play my favorite video games with me head to head or co-op! :)
I was going to say sex but that answer has already been taken so ill say drinking.
you are almost to that age, you will soon find out
sex (its gonna be a constant answer here lol)
Not playing video games.
