For a PS Vita game to be playable without a PS Vita-specific DRM (Digital Rights Management) system or a need for an activation process (often referred to as "nonPDrm" in gaming communities), it usually means the game is either a physical copy or a digital version that doesn't require online activation. However, most digital games on the PlayStation Store, including re-releases and collections, do require a one-time online activation to verify ownership.
The top-rated games or collections usually have high aggregate scores on review platforms like Metacritic or GameRankings.
You're looking for information on a specific game collection for the PlayStation Vita (PS Vita) console.
