So, i'm playing Armored Core, starting with the first one 'cause why not. Cool gaym and everything, but one thing i can't seem to find any information on. What missions should i pick to make sure i get all of them? Right now i'm always starting with the mission that pays the least, but i wonder if maybe this isn't a mistake and some of the higher paid missions are going to disappear from the roster. I'm also guessing Chrome is the "evil" side of the game. Is picking missions indiscriminately going to affect anything?
Disclaimer: Haven't actually played the games in the series before AC2.
That said, I played through the others the same way as you, and simply reloaded my last save if I missed out on any missions. You could probably track down the perfect order in a guide on gamefaqs or something, but if you're trying to avoid missing any missions, presumably you're enjoying them enough that you won't mind replaying one here or there.
Besides, the series as a whole is really long. You'll almost certainly burn out long before you run out of new missions to play.
