4, 5, and zero are the best ones.
And as far as I know, they are the only ones connected to each other in the same world. They are pretty old school though, you’ll need a PS2. BUT, with that said, they are fantastic stories
«»>fantastic stories is putting it so lightly. ace combat 4, i know ever word of every scene and i still tear up. the music is perfect and reflects every scene fantastically. From first learning about yellow thirteen to playing your fathers favourite song on harmonica in the bar with yellow thirteen, the person who indirectly killed said parents. even the scenes with no music are incredible because of just how well it was written and spoken. even the missions are well made in that they go along with the story so well. first seeing yellow 13 in mission and only just not being able to shoot him down and having to flee or die. then later finding out about his wingman (yellow four) and knowing his pain and finding joy in it then getting that joy torn away by his story. finally giving thirteen the dogfight he always dreamt of and winning, only leaving behind fours handkerchief and giving them both as good a burial as they could. i’ve gone way off track and stuff but point is, phenomenal game.
