Haven't played it really until recently, but got into the Metal Slug games in emulation and had a wonderful time. Great series of shoot-em-ups with fun visual designs and a looser feel than the Contra games that makes them feel less intimidating (even if I still have to continue a lot.) 3 especially is fantastic.

From there tried out Neo Turf Masters as the other game by Nazca and it clicked in a way golf games haven't for me in the past and played it for hours on end. Extremely intuitive, pick up and play, and actually good at communicating which clubs to use for what in a way I haven't seen before.
