S!
I see your point Freycinet. But a so called amateur, no pun here, can make a lot if he/she has proper documentation and specifications on the standards required for the job. Hard to do anything if info is vague and you have no real clue what is required. Sure it could take a bit longer from this individual than from a dedicated team, but good instructions take you a long way already.
SoW will be the base for everything when released. Oleg & Team have a base with all the tools required, a ready graphics/physics engine, the knowledge and professionalism. With time it will expand, as have many other games done, for example EVE Online. Even from a different planet literally, this game is continually expanding. So why would SoW be any different in this matter. And this time with SoW Oleg & Team have all the experience from IL-2 and the lessons learned from there. So it gives a huge advantage.
It will be really hard to let go of IL-2 as it has grown on me for the last almost 10 years. Like did EAW before it. But good thing is that IL2 still gets support from TD and Oleg so it will co-exist with SoW quite a time still
Good times ahead for sure..
