So then from what I can see
Dusk and Arland (plus the one that has the girl with the long purple hair?) are the best trilogies?
How is Ryza? I have heard that in getting pitted against 2 its very divisive in that to some it improves on things but to others the first installment wins (I'm pretty sure that the first one is extremely pricey?)
I think I am leaning toward Dusk. The girl in the first Dusk game looks pretty. I read an article and it said the time limit isn't bad in the first two. So its like a slower Harvest Moon or Persons 5 clock?
Dusk and Arland are going to appear archaic in a few instances because the battle system is incredibly basic. The third game in the dusk trilogy itself is also incredibly lackluster.
Arland and Dusk if you're playing the DX versions they came out years later after the originals, but they're still weighed down by having a ton of missables which plagued the earlier atelier games. So if you want to see everything and get all the endings, you'll need a guide because it has a bunch of bullshit conditions for those games where you may have a short window of time to see an event trigger and you have no way of knowing.
Ryza is probably the most open game in the series because you're going to be spending your time opening up and exploring new areas. Once you get The hammer and few other exploration tools you can open up a few of the optional areas. There's zero time constraints however there's a larger focus on battles because there's around a dozen post game bosses. The appeal for ryza is to use the items made by alchemy to explore all the hidden areas to find rare materials, those in turn make the most powerful items.
It has a large alchemy buffing systems where you take gems and use them to enhance your base stats, people are able to abuse this system and take red crystals and turn them into philosopher's stones, reduce them into gems, and then use the gems to duplicate more red crystals. You can get incredibly overpowered through alchemy this way, it's probably the most overpowered in the whole series. Ryza itself doesn't really need a guide because you can't miss anything in the game.
I'd say the three entry points to the series are Ayesha, Sophie, and Ryza. Everything the Arland games did the Dusk games did better, so if you like Dusk then maybe go back to Arland and check out the earlier installments.
If you go with Ayesha and want more, play Escha next and then maybe go back to the DX version of Rorona or play Sophie
If you liked Sophie, play Firis next and then go to Ryza and Ryza 2
If you liked Ryza go to Ryza 2 then go to Sophie if you have not,
The next game in the series is Sophie 2 so you're going to eventually want to play Sophie at some point.
