This is it: The actual arcade machine that contains the original Ms. Pac-Man and Galaga. Okay, so the machine was made in 2001, but it still held the true originals.
Ms. Pac-Man is that really popular maze game in which you play as the miss in action. Run around eating all the dots, avoiding the ghosts, you know the drill!
Since the stand-up version of this machine is pretty much everywhere I've been to, chances are that the machine lets you play as a Ms. Pac-Man that runs as fast as Sonic the Hedgehog! If not, then there should probably be a way how you can change that inside the machine itself.
Galaga is like Space Invaders, but with several improvements. The enemies do stunts in space while moving down towards you, the "boss" aliens can steal your ship, there are bonus levels, and you can even steal your ship BACK, allowing you to shoot DOUBLE the amount of firepower!
Overall, if you are an arcade owner, or just some person who wants an arcade machine in your room, this is for you.
