For this price this collection seems pretty good. A set of three okay to decent B-tier 3D platformers. Round 2 is the remaster released on Steam some time ago. But the devil lies in the first and third game. Kao the Kangaroo's digital release is worse than the retail release. Like retail version it does not support widescreen properly and accepted no inputs from my Xbox One gamepad. What's new in digital release is fullscreen mode being completely broken. Instead of the game rendering at, well, full screen it instead uses windowed mode and changes desktop resolution to match the window. The game also still uses tank controls (like retail PC version) instead of analog controls from Dreamcast port. And because there is no launcher and and no way to change graphic settings in-game, you have to fiddle with an .ini file to change settings. The core game is fine, but I'd rather use my retail copy. By comparison Kao: Mystery of Volcano fares slightly better. Fullscreen mode works (yay?), gamepad works, but it still has its issues from retail version. No proper widescreen support, diagonal movement doesn't work properly on my gamepad, slowing Kao down instead of keeping the speed, and the whole game is more of an expansion to Round 2 than a standalone sequel, lasting for only 2 hours. And English translation is terrible, if you're an English speaker go use the fan translation instead. I'm leaving Kao: Round 2 as last, because I have the least amount of things to say about it. It's easily the best game in the trilogy, but still feels pretty average and after the first world it tends to bore and drag on. Game still stretches on widescreen and has no content from PSP version. Overall, the first game has technical issues not seen in retail version, the second game you probably already own on Steam after multiple giveaways and the third game is a short expansion of the second game. It makes this collection difficult to recommend to a fan of 3D platformers.
