I think that my biggest issue with SSE is that (as has been made clear in other threads about bouys, etc) the developers have tried to enforce a differential between the "game" and their "professional product".
IMHO, this is an error in attitude. I come from a background of playing Microsoft Flight Simulator (MSFS), where the tagline is "As real as it gets". Everything is modelled superbly, from the clouds to the aircraft to the ground textures. You can (you have to, in fact) even programme the flight computer accurately for certain aircraft. Nobody, however, would claim that this could replace a real, "professional" flight simulator.
Maybe that's the point? We're looking for a "home simulator" - after all, it says "simulator" in the product name - yet vstep want to sell us a "game"! I am never going to spend £4000 for a "professional product".
MFSM continues to thrive, even after development has stopped on the product, due to the third party involvement in additional aircraft, sceneries and peripherals. If vstep had worked out a licensing model (In a similar way that Apple oversees Apps for the iPhone and iPad) for access to a SDK, they could have had a nice little earner, and we could have looked forward to all sorts of unexpected goodies on the way.
Comments about the lack of AI traffic, bouys, etc being too "processor intensive" are also confusing to me. These are issues that were addressed by the flight sim community many years ago! In MSFS, you have sliders to adjust AI density, cloud textures, graphics qualities, etc etc. You simply adjust these for what you're after (Want lots of AI traffic in the channel? Simply reduce the boat or sea texture quality a bit! We want "as real as it gets", but let us make the decision about what sacrifices to make to enhance the particular aspects we're looking for!
One last comment: I've seen a few replies from the developers that have been extremely defensive in nature (almost to the point of insult in one thread I read about the lack of bouys). This is wrong, wrong, wrong!! Without customer feedback, your product cannot improve, and that's a long-term recipe for going out of business. If you hadn't thought of something, fair enough; admit it and add it on later (either as a patch or maybe even an "expansion pack" (Make some more money! It works for MSFS!)).
Listen to what your customers are saying!!
Oh, and can we have some bouys, please???
