Outerra can become easily the bed of the next gen flight simulators and those who do not see that in the horizon in my opinion, are motivated by emotional protection of their beloved flight simulators (and I mean the known Flight Simulators developers or followers)... I heard skepticism on Xplane forum toward Outerra and it is clear why....
I believe that Flight Dynamics / Virtual Aerodynamics codes/libraries and capabilities are around since the early days of PC simulation so no new news in that domain...Therefore we see many indie FLight Sims that can appear every now and then and not just MSFS or the "new Commercial" title Xplane10...
However what we do not see in the Flight Simulator titles today, is a new way of simulating the world.
The known Flight Simulator engines are more or less using the same world representation methods that are sometimes more than 10 years old technologically and conceptually in my opinion...
So what can make Outerra stands out of the usual PC Flight Simulation engines that are used for commercial or indie Flight Simulators, is by being first and before everything else, a sort of "next gen" dynamic world simulator or earth simulator.
If Outerra is pushed to simulate dynamicaly and in new ways everything related to atmospheric light, nature per regions, weather, seasons, vegetation, urban developement etc etc. and the interaction of all these together, then adding Flight Dynamics libraries to it would be a peace of cake in my opinion.
For example, XPlane 10 has only 1 seasonal textures set (green) coupled with a nice month switching slider that no matter on what month you put it, your world will remain the same, green... And no matter what real weather phenomenon you download, it could be the big snow storm in Canada, it will happen on green lands...
The reason why no seasonal textures are developed for XP10 is most probably the lack of artistic ressources to create the whole database of textures for fall, winter, spring and summer... And because the engine is based on this 4 seasons textures switching method (as far as I heard on their forum)
To me, this lack of seasonal variation, no matter what the reason is behind not including it in XP10, kills one of the most important immersion factor in a modern simulator engine made in 2011/2012...
No matter how "realistic" XP dynamics are, it is no more the big news in my opinion, we saw flight dynamic capabilities since a long time now and I think in 2012 we want to see an immersible realistic and dynamic world...
Hence, an efficient new method of simulating the dynamic world, like Outerra will reduce allot of the old primitive methods that tried to simulate our planet and required allot of texture developement...
All in all even if I am a very dedicated aviation lover and Flight Simmer, I look forward to see Outerra, before becoming a Flight Simulator engine, to become a super realistic and dynamic earth simulator engine that could make MSFS / Flight and XPlane engines look made of the old old past
Cheers!
