In my day, we didn't have fancy Duel Domes. We played card games with rocks we found on the street. And then we threw them at each other. Come to think of it, it wasn't even card games at all; we just liked to throw rocks at each other. Mostly at me. That's probably why I have so much self loathing.
Could never beat Colosseum, probably because the saving system was atrocious. XD I beat without much trouble, I believe.I adore XD and its prequel but I think I would like them more if I could actually manage to beat them =(
