One thing of note with the Steam Deck is that it CAN stream games from your PC, allowing you access to your whole library. You get access to fewer games in SteamOS (there’s still a ton). You can always look up what games are natively compatible with Steam Deck before you buy. The big ticket games are usually compatible nowadays (Starfield was markedly absent, but BG3 is there all-the-way).
I know. That one where the first person’s wrist just flows into the next person’s ankle.
