[Switch] Persona 4 Arena Ultimax $13.49 (70% off) @ Nintendo eShop

As far as I'm aware, this is a new all time low for the PC/PS4/Switch re-release of the game.
One disadvantage of the Switch version is that it's the only version in the re-release that doesn't get "rollback netcode", though if you don't plan to play the game online and/or don't even know what it means, then it probably won't matter to you either way.

For those not familiar with it, this version of the game bundles both Persona 4 Arena Ultimax (the second game in the P4A series) plus all DLC contents, and the entirety of the first Persona 4 Arena game's story.

Despite the name, the P4A series is a spin-off sequel to both Persona 3 and Persona 4, so potential spoiler warning for those who have come into the Persona series relatively recently, and haven't finished playing through Persona 3 Reloaded yet.

P4A is easy for even people who are usually not fans of fighting games to get into, due to auto-combos. For single player, intermixed with the battles is two full games' worth of visual novel storytelling, covering multiple character's perspectives.

This was one of my favourite games on the PS3, and at this price, more than happy to double-dip.
