I will mention that you can stream your PS4 and PS5 games to your Deck with the chiaki and chiaki4deck programs. But the initial setup can be a little annoying and may confuse some people.

I cant even think of any exclusives. :) I will say be sure to watch the HumbleBundle site for often great deals to fill up your steam library, and there are numerous Free give away games from sites like GOG, and Epic, and the Amazon prime Gaming, which can be played on the Deck with helpers like “Heroic Games Launcher” or “Lutris”.

Then theres the HUGE emulation area, which can keep you busy for a long long time. Numerous GameCube Classics run great on the Deck. (and others)

Good Luck - the Deck is one of (if not THE) most versatile and flexible game system out.

I would say that adult only games are exclusive to the PC. I feel that PC often get multi platform games first. I saw Dredge and Dave the Diver on Steam before any other consoles.

WitchSpring R is a new game that runs very well on the OLED SD, looks good too. Is a JRPG, starts of a little slow (not necessarily a bad thing), has decent combat with a reasonable amount of customization.

There aren’t a lot of games that aren’t multiplatform at this point, and I haven’t personally tested more than WitchSpring R so far on my OLED SD, so while there are other games that are checkmarked that I know are good, I can’t recommend them without seeing the performance first-hand.

I also play mostly on consoles and was pretty happy browsing the early access section, since most of the stuff there will not be on console atm (some Xbox game pass game preview but not that many)
