God, I have a lot of fond memories of this game. Probably one of my favorite "classic" (vintage?) RPGs.
The seven songs that play after the defeat of the final boss all the way to the credits have been a permanent playlist on my phone for the last decade (I like to call it the Wild Arms Ending Suite). Michiko Naruke is an amazing composer!

Incidentally, I got this game as a PS1 classic for my 16th birthday along with Final Fantasy XIII. Kinda funny that the game I got as an afterthought stuck with me a lot longer. Hell, it introduced me to Trigun, arguably my favorite manga.
