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.
Be sure to learn how to harness the power of the AnimationPlayer node. You can make function calls and all sorts of property changes at key points of any animation. So, instead of writing code to check if a certain animation has begun and doing something, you can just call a function at 0.0 (start) of that animation. I'm doing this to spawn projectiles from a bow shooting enemy, it works like a charm.
