I had a feeling I would be the only one to give Zone of the Enders points ddddddd. Picking a #20 spot was difficult because there were so many games I could I have used. The reason I went with this game was not only because I had a lot of fun playing it but it was my first encounter with a game centered around Mechas and part of the reason I still find Mechas so cool. Young me was in love with how great the world looked and it felt like I was in the future. I didn't even buy the game, though. When I was a kid one of my parents' friends gave it to us along with an E.T. VHS and some other random things. I was unaware of its status as a cult classic until I looked it up for my list but it's honestly what she deserves. Oh, and it has an OVA and two anime series but I haven't seen those ddddddd. The music was quite fun as well. It's honestly been so long since I have gone through it again but I have very fond memories of it. 10/10 would recommend.
Here's a bit of gameplay of it for anyone who wants to get a quick glimpse of it.
Edit: Looking at some of the suits now makes me think of Neon Genesis Evangelion.
