This is a highly underrated online and (now with its latest update) offline party/competitive game that has flown under a lot of people's radar since Nintendo's unveiling at their E3 presentation in 2018.
This game features online co-op play for up to 4 people in 4v4 games with 3 different paths to victory. The latest update allows for 8 player local play (using one console) as well for parties or situations where internet may not be available.
Full crossplay support is promised when the game releases on other platforms, but for the time being the game is only out on Switch and PC. Crossplay works seamlessly, but servers have been a little lonely lately due to lack of promotion and visibility surrounding this title.
The game is quite highly reviewed and I definitely recommend it!!
I keep reading that I should play it but I've looked at a couple of videos and it looks unappealing to me. Lonely servers don't sound appealing either.
