That is not exclusive for Razbam. ED does the same thing, launching half finished products at retail price.
I think it's a common thing in the sim world. Even the A-10C after almost a decade still has bugs like the LASTE wind correction (it never worked, like some none real pilots think).
I also think the DCS platform encourages this, having tons of modules and not even one of them is 100% finished.
Dont get me wrong (those who will jump at my throat), I love DCS and will keep using it all my life if it's still there. But I wont stop saying what I feel, even if I buy their products.
