From farming the Return to Ivalice raids in FFXIV for the new Relic, my (perhaps boredom addled) brain decided that it would be a fantastic idea to do a full Ivalice playthrough some time, and I proceeded to eBay the DS games I was missing.

I won't be doing this quickly or even immediately, but I was wondering if anyone had any tips or pointers for any of the games or stories or anything for when I get around to doing it? (other than Fynn saying not to play Revenant Wings)

I completed FFXII back when it released, and played 80% of Vagrant Story when it released as well, but haven't touched them a great deal since then, and only ever dipped into Tactics (but I've played Tactics Ogre, Fire Emblem etc)
