If you are old enough to have experience with actual arcade games, coin ups, etc, what's your absolutely number one? I am sure you have several near the top, but what is the one? For me it is Exerion by Jaleco. Released in 1983. A vertical scrolling shoot 'em up where your fighter plane has two types of shots and no others, no bonuses etc. You have a limited number of single shots which fire very very fast and an unlimited double shots which fire slow. The game also has an inertia mechanic where your craft takes time and some effort to change direction and speed. Making it perhaps the first game of its type to use physics, basic as it is. The game was also gorgeous to look at in the day and using the very good vertical scrolling provides a depth effect, almost 3D not seen often. For me it is a fantastic game which unfortunately isn't as well known as many other games of the time/type. I was lucky enough to find it available on the PSN store (would LOVE a physical release, but that is never going to happen) and I got it some time ago. It is not a game you can play easily with a gamepad though. You better use an arcade stick for it. Also it is perhaps the first time I used the PS4's built in recording option to record a session (not that good, but who cares) and I then uploaded it to my channel because this game needs recognition. Just a gameplay session, no commentary etc. So, what is your favorite, number one, arcade game of all time, if you have experience with arcade games.
