This makes the default be a single list, the same list for all of
them. If you want the default to be "construct a new list", you'll
need something else:
def __init__(self, games=None):
if games is None: games = []
There is an open proposal to allow this syntax, which would do what you want:
def __init__(self, games=>[]):
However, this is not part of any current version of Python.
