I've been sinking further and further into the RetroDECK time-sink of setting up my emulators just so, and having the most fun doing so. The PS2 is a largely unknown system to me, I neither had one nor spent much time before now playing through some titles.
So...this is what I have so far! Most have either HD texture packs (Rule of Rose for example, and also Silent Hill 2 has a incredibly big 29GB of HD textures, I added after taking this screenshot), or mods applied (Gran Turismo is Spec II)
I haven't got MGS3 there, as I'm waiting for the remake to arrive, but...
Can anyone suggest any titles which are 'must adds' for me? I'd appreciate it!
It's a little cringe in retrospect, but I really liked my time with Makai Kingdom. Avoid if anime stuff isn't your bag.
Ico had some interesting ideas that are worth a look.
Rogue Galaxy was pretty okay.
Psychonauts deserves a mention, though it's kind of obvious.
Red Faction had cool political leanings for a game of that era.
You've got heaps of great suggestions already so I'll leave it at that.
