If you don't really care about portability, I would say the most ideal way to experience this game is to get the PS4 version or the PC port, as they're both cheaper and a more fluid way to play the game. But if you want to play the game on the go, then this the version for you.
This original release is still a bit of a disappointment and leaves a mixed impression. If you are looking for a solid JRPG for Vita, this is a fully complete game, but for those wanting the absolute entire package, I would recommend waiting for the definitive version.
ClaDun Returns might not be everyone's cup of tea, but it will definitely fill a void for players who want a throwback to something from the retro days that displays strong fundamentals towards its dungeon crawling roots. The game is loaded with content as there are tons of stages, and its compact brevity is ideal for portable playthroughs. Unfortunately, this same feature is also holding the game back, making it an extremely repetitively and somewhat flawed experience.
