Guitar Hero 1, 2, 3, world tour, 5, warriors of rock.
I didn't include the single band games, the lego games or DJ hero because I was not including spinoffs for the other franchises - main series only. I suppose I missed the main series portable games and band hero
And yeah, some sports franchises have more than 1 per year, 1 is the standard though
