Just got my first PS2 emulator to work

Haven't even got to the series yet unfortunately

The Sly Cooper trilogy runs very well on PCSX2, as well as Final Fantasy 10 and 12. Those might be a good start.

kingdom hearts, simpsons hit n run, and every ace combat

I would recommend the Yakuza games. They're sort of open world games with fun combat, a great story with memorable characters, and groovy music.

Also check out the Siren games if you hated the Silent Hill games being too easy, they aren't for everyone, but they'll certainly click with some.

Warship Gunner 1 and 2 are both great games.

I'd also recommend Way of the Samurai, Trapt and Global Defence Force.

I wonder how large an .iso collection of all of those games would be.

Why?

I've got close to 100 PS2 games on my PS3 and its netting about 500GBs or so. The whole chart is probably over 1tb or so.

Again, I don't remember too much as I just downloaded Generations set with II & III and plan on replaying them for the first time in like ten years, but what I remember of GRL2 was:

I remember liking it cause it was a bit like Final Fantasy Tactics except the battle system seemed more sophisticated and fluid

Drakengard
SMT Nocturne
SMT Digital Devil Saga
Dark Cloud
God Hand

Those I'm currently playing a lot.

I also finished downloading pic related.

I don't think I saw it on anyone's charts. It kinda flew under the radar back in the day but my older brother used to play the shit out of it and I think he liked it better than God of War. I never got the chance to play it though, so any review would be nice.
