Hopefully future space wars wont be fought this way
Think about every movie you've seen with dog-fighting in it. No, not the animal abuse kind, the planes kind. There were always wing-men, so it was almost never one guy verses a thousand other planes. But the guys in charge of arcade machines said "Screw that, make it one guy verses infinity dudes, and put it in space.", and so began the consumption of millions of quarters. Fast forward decades later, after the death of arcades as a sustainable business model outside of Japan (if you have sad music play it now), and now you dont need quarters to play those games.

Long story short, twelve arcade "space shooter" games have been made available online to play free from your browser, including R-Type and Space Invaders. If you like high scores, space ships, power ups, and blowing up incredibly fragile alien spaceships with an incredibly fragile spaceship of your own, then you should love this.
