I still have "Raptor: Call of the Shadows" on my computer that I play from time to time. It is "Xevious" with better graphics.

A lot of old games can be gotten for $6 or less from GOG.com. Many come with 'wrappers' so that they can be easily installed and played on modern computers.
I had a friend who was an engineer at Bally/Midway Manufacturing. He left town after the company folded. His basement was packed with video arcade and pinball machines (no quarters needed, just bring beer). A few of us would spend whole weekends at his house. I still have a table model of Ms Pac-Man he gave me (in my basement gathering cobwebs).
Edit:
Adjusted GOG.com game cost. Just checked, prices have gone up.
