Mega Man (PC)
Mega Man for DOS features something like an Opening Stage, with Mega Man walking along a straight path to enter what seems to be a part of Dr. Wily's Castle, the only enemy appearing being a dog-like robot vaguely resembling Velguarder which respawns indefinitely. The stage ends when Mega Man passes through a boss-room-esque door. This can be considered the first Opening stage in a Mega Man game.
