If a guy has no game, does it mean he's a nice guy?

So guy calls 2 hours after getting my number and asks me out. That's never happened but I thought it was sweet. I couldn't make it. He seemed disappointed.

I hate games so I liked how real and genuine he is. I'm really attracted to that. I've gone for jerks in past so a nice guy is what I'm after.

Why is it guys claim it means he has no game, just because he didn't leave me waiting and actually followed through after saying he would call.

Anyway I called to rearrange. We did and he didn't get back to me. I guess his friends had a word or he thought he was being too forward. He's left me hanging a bit unless something came up.
