If you feel like you have to resort to games, you are not really great friends. Great friends are able to communicate with each other. Talk to him already!
And just like in any relationship, different people have different communication styles. Maybe he isn't someone who does a lot of contacting, no matter what. That doesn't mean that he doesn't care. It might just be the way he is. And then you just have to decide if you can handle that.
But, until you TALK to him, you will never know.
