You already have an insanely good library. You could probably play for the rest of the year on those games alone. In addition to what you have here, I’d recommend:

Alien Hominid Baldur’s Gate: Dark Alliance Burnout series Def Jam: Fight for NY Destroy All Humans 1 & 2 Devil May Cry Godfather, The GTA Vice City Stories & Liberty City Stories (NOT ON PC) GUN Hitman: Blood Money Jak & Daxter series Lord of the Rings: Aragorn’s Quest Marvel: Ultimate Alliance Marvel vs Capcom 2 Need For Speed Underground & Hot Pursuit series Onimusha: Warlords Psychonauts Ratchet & Clank Series Rayman 2 Resident Evil 4 Red Dead Revolver Sly Cooper 1 & 3 (1 & 3 are probably my favs) Shadow of the Colossus Silent Hill 2 & 3 Simpsons Hit & Run SoulCalibur II Spider-Man 2 (phenomenal free roam) Star Wars Battlefront I & II Super Monkey Ball Deluxe Tony Hawk’s Pro Skater 3 Twisted Metal: Black

FWIW, the original PS2 versions of the GTA games that are also on PC are actually better because they removed content as licenses expired. Unless you have the downgraded PC versions - in which case, godspeed.

Even then, I usually stick with PS2 as PC doesn’t have support for the analog face buttons that the PS2 had. I don’t know if you can emulate that on Steam Deck, but if you play PS2 GTA San Andreas with an OEM controller, pressing the button harder actually does make you go faster. It’s magic, and I find it hard to play without now. 😅

I look forward to seeing how the Deck holds up with some of these titles! I’ll admit, I’ve been thinking about getting it to use as a portable PS2 myself.
