I sure hope theses titles hit the US market for 3DS as well. I already own Mega Man 2 on every device except for my blender. But one more copy of Mega Man 2 never hurts my feelings.
Double Dragon 2 is also nice, but I wonder: what about 2-player? does it even support it? It would be pretty awesome if it did support 2 3DS consoles to connect and play that game together. It's one of my favorites - but like many others it's much better played with a friend.
