Are these signs that he likes me?

He's my DM for dungeons and dragons... haha. I've been told so many times that being a pretty gamer makes me quite a catch that I actually believe it now, though I don't let it get to my head.

He seemed impressed with all the preparation I'd done, and helped me create my character. I finished quickly, and we chatted about all sorts of random things. He seemed excited that a girl would express an interest in what games are being released next year. He sat next to me while we all played, and the game seemed to be in my favor. At the end, my friend and I were leaving and he gave me a hug. It was adorable.

Being a major geek (nothing against them. I am one), is this normal behavior, or is this just his discreet ways of dealing with girls?
