Ah, so I've noticed some of you were asking if they chose G1 only, could they still keep the other gens they had and vice versa. I guess I didn't consider that when I posted this question. Well, I intended you could only have what ever option you chose. So if you chose G1 only, you would have to forgo the other gens you already had. Sorry! But as someone stated, good thing this is only hypothetical! That's what makes them so fun, right?
