The first official release of DCL dropped today. 15% off for a limited period (until 25th February 2020). 

However, even with the discount, it's still more expensive in comparison to the other top level simulators, so I think expectations are probably going to be quite high. I've not played it so I can't give any insight or feedback as to how it compares to the other sims.

Full price is $29.99, down to $25.49 with the discount.

Actually it´s quite good simulator, absolutely the best looking one. I can even feel the prop wash in the game. Optimalisation is very good - high details on I5 8400 with 1060 GB with stable 60fps with VSYNC ON. The sense of speed is also good in the game. Only one thing I don´t like - the quads feel very light in the air ( even bigger quads ) and falldonws with no throttle are too slow IHMO. It would be nice if the gravitational force was adjustable.

Tested during free sale weekend and bought it after month for full price   
I played 5 hours so far. 

I have also DRL SIM and Velocidrone. I´ve refunded Liftoff - didn´t like it for the price but I´ve read about new physics and maybe I will try it one more time. But I flew around Josqhua´s house
