The PlayStation Vita was Sony's last stab at a truly portable game console — the PlayStation Portal (which is worth buying) doesn't count since you need an internet connection to play. Sony might be phasing out Vita support, but modders are keeping it alive thanks to mods and hacks, and you can now use them to play Xbox titles on the Vita. This program can connect to Xbox Cloud Gaming and stream titles directly onto the Vita. As GreenVita relies on Xbox Cloud Gaming, you need an appropriate Xbox Game Pass subscription and a stable internet connection. Plus, you will be limited to whatever games Microsoft provides for its cloud gaming service.
