While I agree with the objections concerning ROF, I consider it nescesary to point out that the DRM present in Black Shark (yes, StarForce) is in no way similar to what people have become to loathe.
It kept me from a day-1 purchase, in fact it kept me from purchasing untill about a month ago, untill I realised my hatred towards the name StarForce was, in this case, unfounded.
Ofcourse it depends on where you draw the line when it comes to restrictions. In this case there's an online activation with limited activations. If you're migrating to a new system or doing an upgrade, you can use a deactivation and reactivate after you've made the system changes, without losing an activation. No rootkit-like driver installs that can mess up your system.
I still don't like it when anything is "limited", but it still beats the restrictions found on many other games (pretty much anything that has SecuROM nowadays).
If you can look past the StarForce name, you might find that the system is in this case quite reasonable.
As far as flight
simulations go, it's the best thing ever. Eagle Dynamics both needs and deserves your support. Perhaps they might even drop StarForce in future modules.
