A game for 4 year olds

[Absimiliard]

70,000 Dalmascans died in 1 battle against the Garleans at Nalbina Fortress. Dalmasca and Nhalmasque were taken by overwhelming force through the use of airships and then conscripted their citizens to fight their wars against other nations.

Note the word "mostly" in my initial observation. The Garleans didn't really stand to gain much from conquering a bunch of ruins and dead bodies, which the game does tell us. Doesn't meant there haven't been times they employed extreme force. It just means it's probably not going to be their go-to if it can be helped. If they really wanted to just "win" they could've ended nearly every war they started almost immediately by fielding a bunch of airships and turning every country they visited into a smoking crater.

The Garleans will probably have their own reconciliation storyline eventually, now that we just got over their collapse. They're more central to the plot of the game after all.

I have a sneaking suspicion this may not occur, or if it does it won't be for a good while. The developers were looking to push the game away from Venat, the Ascians, Garlemald, etc. with Endwalker. Their original, more in-depth plans were scrapped in favor of the quicker approach. At any rate, if moving on with the story is the objective, then Garlemald may well not be touched again for a long time.
