My opinios is that developer slowly but surely should stop developing new products for FS9, because in that way, the code isn't FSX only and at the end FSX user always have to deal with errors and bugs in the program caused by a non native FSX code. I mean Flight Simulator 2004 got released in fall 2003, that's nearly 8 1/2 years, let's be honest, in other game sections, no one would still play such an ''old'' game when there would be a sequel already. (Ok, now two but I don't count Microsoft Flight as a simulator as FSX, FS9... it is) I don't have any problems when people still use FS 2004 as it just needs much less hardware performance and I even understand people who don't want to change even if their system would pass FSX but who have purchased a huge amount of FS 2004 addons and everyone knows that the FS addons aren't that cheap. No, the only thing I want to mention is that you've to decide whether you go with the times or not. If you decide to keep playing FS 2004, then you even have to live with the thoughts that some new products won't be available for FS 2004 anymore. It's just time to go forward. I'm not a developer so I actually don't know the exact work when creating an addon, but I think it'd be better if developers release two seperate FS versions. One for FS 2004 only and with FS 2004 code and one for FSX only and with native FSX code so there wouldn't be that much erros anymore. Perhaps I'm totally wrong, then I apologize for every lie I said, but it's just my idea.
