Is Poker Night 2 on PSP? No

No. Poker Night 2 (2013) was released on PC (Steam), Mac, Linux, Xbox 360 (XBLA), PlayStation 3 (PSN), and iOS. It was never ported to PSP or PS Vita.

Why No PSP Version?

• Engine Constraints: Telltale's proprietary toolset targeted Shader Model 3.0+ GPUs; PSP's fixed-function hardware couldn't run it without a full rewrite.
• Market Timing: PSP was winding down (Vita launched 2012); digital-only XBLA/PSN/Steam was the priority.
• Storage: 1.5+ GB install size exceeded typical Memory Stick Pro Duo capacity for many users.

How to Play on Portable Today

• Steam Deck / ROG Ally / Legion Go: Runs natively (Linux/Windows), excellent controls.
• iOS (Legacy): Pulled from App Store ~2017; only works if previously purchased on same Apple ID (iOS 11 or earlier—32-bit app).
• Xbox 360 / PS3: Still purchasable on legacy stores (while they remain open).
• PC (Steam): Best version—mod support, 60 FPS, all unlocks.

If you want poker on original PSP, try World Series of Poker: Tournament of Champions or Poker Night at the Inventory (not on PSP either—homebrew only).
