I'm not going to play a $60 game my friend bought me without asking if I wanted it
Are you serious? Why wouldn't you at least try the game that your friend got you?
I would proably like it, but I have a lot of other games to play.
Even if you you've lots of other games to play, you should consider trying the game your friend got you. They went to the trouble and expense to buy it, so you should show them the courtesy of using it. Besides, if they thought you'd like it, you might be surprised and actually love it.
Nah, I'm a busy guy and don't have time to play it.
I think you should at least play some of the game so that he feels appreciated. He gave you a nice gift and you should be grateful.
