When I first played the Neo Geo at my local game store the two that got me hooked were Magical Drop 3 and Blazing Star. Even though I enjoy Pulstar more nowadays, I’ll go with those two titles which got me started with the platform.
It's an iconic game that requires a ton of practice. Perfect two slot game too as the player won't be distracted by ponytail weaboo bullshit offerings. I only threw in Magi Lord as a pallette cleanser because alongside Nam it sounds amazing
