I like Cap and the GR. They produce easy to understand tutorials, however, his passion is obvs cold war era jets. That's fine but what makes a simulation great is choice. I never understand people banging on about certain jets or weapon systems. If one is wanting to play a balanced game online, then just remove the option 'in-game' on certain systems.
I'm a SP & as long as the systems are accurate (as much as possibly known), then I'm happy. I love the JF17 and the reason I play DCS. I love it's systems. I love modern weapons technology as well as 'retarded' technology. What's great about DCS is, I have choice to deploy these systems, or not.
If DCS was about a certain specific era jets or nationality of jets, I would not play it.
Keep the simulation open and interesting and leave it to the consumer how they want to play the sim.
