Hi Mathijs First of all congratulations to the project. This is the right way to go and to improve the simulator world for everybody. Things I would like to see in a new simulator - blade element (like X-Plane has) rather than lookup tables - crossplatform compatible simulator not only Windows but also MAC and Linux. I hear you already moaning, but if you have learned the lesson MS taught you as a Addon-Maker with the closure of the MSFS departement, you are still in their hands when it comes to the OS-system (and they will use their power, you bet). This is in your hands now to become independent from MS if necessary. I don't say you should give up producing for Windows , it is a wide spread OS and will be around in the future. BUT don't bind yourself too much to it, be flexible for your on sake. OpenGL is a powerful 3D acceleration runs on crossplatforms, there is no need to go for DirectX. - Go for Opensource. I know, you want to make money with the new simulator you want to develope. But you are asking what we/I want. I like opensource as I see that it brings the best quality through the openness. AND most of all, if Aerosoft decides to abuse their market position like MS or to stop the developement, then we stand in the rain again like we do now with the MSFS. Opensource would mean, that somebody else could take the code and develope it further. Ok, these are my 2 cts. Good luck with the project and I will follow this closely. For now I stick to X-Plane which I use since 2006 with great joy and which I see improving fast in the last years. Mathijs, it is good to have a competitor again because this keeps Austin Meyer from getting lazy . Cheers Chris
