DCS is a mixed bag. On the one hand you have the companies that release broken DLC that never seem able to fix it. On that hand Id call VEAO which seem to have gone tits up and never seem to have suceeded in fixing the buggy hawk.. There are those whom have extended development but slowly get there, of which I would probably tag razbam. And there are those whom seem fairly quickly to get a completed product. Belsimtek (whom ED have now bought) fitted into that margin. Its a real mixed bag.
My main concerns I have over ED is banning anyone that disagree with some of their choices, or their fairly piss poor relations with the community. Im think of Lock On files, whom seem to have had a major falling out with them because people were releasing what ED considered were exceeding the EULA. Against that you have some of the individulal DLC makers, such as Razbam, that have actually gone so far as to employ a community relations employee, and things for that have improved markedly.
There are worse out there. Its worth looking at flight sim world. Ive sympathy for the choices they made, but pulling the product after only 6 months is pretty freaking bad whichever way you look at it, particularly when it cost something like 30 squid.
