Any of the Suikoden games really. Legend of legaia 2

Ephemeral Fantasia for an extremely underrated gem.

How is XIII via emulation? Would love to try that on my Steam Deck.

Silent Hill 2

There are two amazing super hero games that I would recommend: Spider-Man 2 and Hulk: Ultimate destruction.

Spider-Man 2 was easily one of my favorite games of all time. This game essentially set the bar for what a Spider-Man game should be.

Hulk: Ultimate Destruction was an open world game where you were the Hulk and did all the Hulk things. I can't think of a recent game where you play as the green giant.

If you're a fan of the anime, the .Hack// games hold up pretty well. There's a little OVA that is included with each game to give more story.

Gauntlet: Dark Legacy is great classic fun

Def Jam 2: Fight for NY. It's basically like some of the older WWF wresling games where there can be 4 fighters at a time, but you can only be targetting one at a time. But all the fighters are rappers. The finishing moves are awesome!

Ace Combat Zero! Or 4, 5, and Zero (in that order) if you want a lot of it.

Dark Cloud 2

The Soul Reaver / Blood Omen games have not been recommended yet. Though, as a warning, last time I tried to do the Soul Reaver 2, there was a strange bug with the sound that made it so that you couldn't pass a certain puzzle.

Soul reaver

Grand teresmo

Rayman 2

I absolutely loved KH1/2 FM

...so grain of salt, cuz the name of this one doesn't sound right, but the screenshots look correct: Gradius V?

Side scroller arcade-y jet fighter - I remember it being good.

I just don't remember it being called Gradius >_<

Downhill Domination is... honestly stupid as all hell, but by design: it's a lot of fun :P

It's a downhill mountain bike racing game with a combat system, and it's ridiculous. You start being able to punch the bicyclists next to you; once you knock enough of them off their bikes you upgrade to being able to kick; then iirc you eventually get a stick or something lol. Otherwise, it's just another get-from-point-A-to-B-as-fast-as-possible game that doesn't require a lot of thought.

Try out Shin Megami Tensei: Digital Devil Saga 1 and 2. It's one of those JRPG games with a lot of mysteries and loose threads and every single one of them end up solved by the end.

All the GTA games (GTA III, GTA VC, GTA SA, GTA LCS, GTA VCS). There are some good Need for Speed games too, and a bunch of great Tony Hawk games. TimeSplitters, SOCOM, and Red Faction are great too.

Arc the lad 2 twilight of spirits is a cult classic

Jak 3

Dance Dance Revolution!

Ratchet and Clank games

My entire childhood was Tony Hawk's Underground 2 on the PS2.

Crash Nitro Kart and some of the PS2 Crash platformers are pretty good. The Kart one has a boosting system that I like better than mario kart (and better items and vibes tbh)

Ps2 Mortal Kombat games were the best, they have beem sliding ever since.

Deadly Alliance is a slog for story/Konquest but a fun game.

Deception is so so good, one of my favourite games ever. Doesnt really hold up as well as Id like but it has brilliant features that I miss in every modern iteration. Namely the best konquest implementation. Chess Kombat.

Shaolin Monks, another one on par with Deception. I have to replay this next.

Armageddon is carnage, just fun fun all the way through. Every character from the entire run of the franchise is playable, it is everythimg.

Not exactly a suggestion, but why emulate Okami instead of just running the PC version?

Edit: If you get the PC version, you should be able to use the touch screen to draw the brush techniques directly thanks to mouse support rather than having to fuck with the sticks. You also don't get the input lag from emulation.

Id look up the GT4 spec II mod. it adds a bunch of features to the game and even the Valencia track from Tourist Trophy

Klonoa 2

Super Monkey Ball Deluxe

Beatmania IIDX (if you don't mind connecting a keyboard to play)
