No, I just mean that some aircraft come with almost no instrumentation. So, a Sopwith Camel + field mods is about $9.62, but a Nieuport 28 + field mods is about $12.62, but you end up with the same instrumentation. I dunno, I understand the need for revenue, but it seems unfortunate that it works out that some aircraft cost more to get the same stuff.
Well, I doubt that the entente and central powers had agreed on a nominal fighterplane standard and cost during the real world war..! ;-)
Seriously though... I see your point, and it's a good one. However, different products has different standards, and different prices.
For instance, some aircraft may be harder to research, and require more creative modeling and programming, which equals time - and time is money. Yet they cost the same... Is that fair?
I think the most important factor here is that the DLC products keep the developer in business and the users get high quality content.
I feel that I get my moneys worth, and then some. Others may disagree.
One thing we all seem to agree to is that Rise of Flight is a damn good sim! :-)
