Okay so this is a weird one, and I'll explain why.
This game launches next week across all platforms, but, in Australia at least, there is a heavy Switch tax. On both PS4 and XB1 the game is listed at ~$49 at EB Games and JB Hi Fi, whereas the Switch version is listed at ~$69 at the same stores.
Currently Amazon are price matching the European copy available from OzGameShop and have the other platforms listed at ~$43 and ~$49 respectively.
Now on to the game:
This is not a direct sequel to Yooka Laylee, the 3D platformer, but rather a spin off in the style of the Donkey Kong Country series.
When developing the game, Playtonic were targeting a smooth 60fps experience on Switch and then enhancing the visual fidelity and effects for the more powerful systems. This is a game built from the ground up for Nintendo's system in other words.
Here's some gameplay from an early copy of the Switch version so you can see the smooth performance for yourself:

Anyway, by preordering you're saving roughly $21 from RRP on this version of the game or at least until Big W or Target come in with a lower offer closer to release.
You are also protected by Amazon's pre-order Price guarantee.
