Not sure if checking out PSO at this point is really worth it.
I'm not expecting to get much gameplay and enjoyment value out of it, just want to give it a spin to satisfy my curiosity.
PSO2, shockingly enough, is quite a great successor. I wish I had the life where I could put in the time that it requires. I don't though, so don't bother.
When I played it a few years ago it was a good game to just pickup whenever and just play a mission or two. If I hadn't switched to Linux I might still be playing today.
Dark Force's scheme to beat your team to Rykros was presumably an effort to stop them from aquiring the Rings.
They originally introduced Rykors as a place of all knowledge. Then it was just a place where someone tells people about the Algol system and PD. I expected much more! Before the exposition scene on Ryukros after clearing the towers it appeared to me like PD aimed to gain control over spacetime, and that Dark Falz appears every thousand years in the Algol system because it's vaguely tracing the orbit of Ryukros.
btw the illustrations of the Saturn collection has an image with Dark Falz written in roman letters as "Dark Phallus". No idea where they were going with this thing if this is the intended reading lol
