Well, to each their own. Gotta note, though, that the vanilla and Zodiac Job System PS2 versions are more challenging than the Zodiac Age version.
This is quite a nice summary! Yeah, the stagger meter is an awesome addition, especially since you have to take into account how exactly you reach the stagger. Do it with three ravagers too fast, and it runs out before you amass enough damage, for example.
My only issue with this battle system is that oftentimes, if you screw up your tactics, the game punishes you with prolonged combat instead of a game over. No MP, nothing to run out of, but you have to be effective so that battles don't drag too long.
XVI looks like an Ivalice-setting game to me, but without the tactical approach of XII/Tactics. I enjoyed the story for what it was, but felt that the game tried too hard to be like one of the ~~cool kids~~ classic installations in the series. It didn't have a new idea, a spark behind it, only a concept that it has to have all notable FF elements like familiar summons, moogles, enemies, weapons, etc. But it's a good game overall, didn't go through development hell like XV and sold well.
Thanks, but it's pretty dead at the moment.
I've played Tactics only this year and was surprised how much XII resembles it in mechanics despite these games belonging to different RPG subgenres. It lead me to think that XII only happened because there was this proper foundation of Tactics, so I doubt there'd ever be another mainline game in Ivalice, but more Tactics games are possible, I think.
I wish I'll have enough time at some point to get to the Ivalice storyline in XIV.
