Game has extemely solid core mechanics but everything else surrounding it pretty much sucks.
Yeah, I'm a bit suprised this reviewed so well. Could be a very good game, the basics are all there, but feels like it would have needed another six months. Really hope this will get the support it deserves. Don't care about singleplayer personally, but more options and QoL improvements are a must.
It's got the Mario brand attached to it.
My copy from Amazon arrived yesterday and I spent the whole afternoon/evening with it.
Attention, horrible (but true) analogy incoming:
Mario Tennis Aces is like an amazing, juicy steak (core gameplay mechanics), that is overcooked on some parts (adventure mode) and very small to begin with. The steak also doesn't come with any side dishes (outfits, rackets) and the forks are clumsy to handle (menus).
Unless you are really into steak and able to appreciate it, you shouldn't order it.
