This is of course not including the yearly Unity subscription, where Unity Pro costs $2,040 per seat (although they may have Enterprise pricing)
Absolutely ridiculous. Many Unity devs are saying they're switching engines on social media.
Will Garry Newman decide to reskill his devs to use Godot?
Ehhh, I doubt it. His team is currently working on Source 2 for their game S&Box. I would expect he's pretty close with Valve so he might just use Source 2 for the foreseeable future.
