/vr/ - Retro Games

What game would you guys say is it? Please state why. (Pic unrelated to me even if I still like it)
I don't have a strong opinion, it's hard for me to decide, the closest would probably be Mars Matrix for me mainly due to its sheer intensity. I'm curious to see a discussion about this topic here.

What games I include: They must be 2D, (polygon/prerendered graphics are ok, just 2D movement), auto-scroll, have 8 directional movement independent of the main auto-scrolling and of course be about shooting and dodging enemy hazards.
This means I'm pretty flexible, you can include arcade ones or ports, made for console, pc doujins and even euroshmups.

If you don't enjoy nor plan to play the genre please refrain from posting. Thank you, we get too much shitposting in these threads.
