Valve's repentance for Artifact

[caffeinade]

So for people who don't know; Valve announced a New game: a card game called Artifact.

The reception has been less than positive, for obvious reasons.

I feel Valve has to something to repair their damaged public perception, and I have the perfect solution: a kart racer.
Valve has a lot of really popular characters, they understand game design, they are perfect for the job.


Chell, she can shoot a portal in front of her that exits a few meters behind her.
This can be used to either portal away from danger, or to punish other players.

Charger, has a short dash that uses up stamina / fuel.
Dash can be used to: avoid attacks, open up shortcuts and / or bump other players.

Gordon Freeman, has a gravity gun and a crowbar.
Pretty obvious what this could do.

Scout, can double jump.
Jump over obstacles and other players.

Add in a couple more characters like Dog, Wheatley, Gabe Newell, Pyro, a few people from Dota, Counter Strike and a few from their other games.
You have a instant classic.

Kart part skins and character skins; instant money.

What do you guys think?
How else could Valve make money off such a game?
