I don't think SF is going to die. It has too much to offer. It is more of a sim than an arcade game. It has open architecture. The frame rates are great even at high res. It presents nothing but open ended possibilities. Hard to find all of that very often these days!
As regards pricing and location in stores, that's all business. If you had just released CFS3 would you want SF sitting on the shelf next to it? In addition, haven't you noticed how much more space is being given in stores to X-box and similar players and how space is being taken away from the ever shrinking array of PC games? It's war out there. Companies want to promote their products while at the same time squashing the competition. It appears to me that there is an all out effort at consolidation and moving everyone from PC games to game box games. Only problem is there won't be any high quality air combat sims.
As regards LOMAC, all I can say is that I don't see it as an either/or situation. I cannot speak for others and I have no control over the decisions of others so I don't spend much time thinking about that sort of stuff.
Regardless of what happens I am happy that I purchased SF. I want to support any efforts to bring forth new combat flight sims. SF is a bold effort. Even if it did "die", if I didn't already own it I would buy it after it "died" because I would like to see more efforts in the future along the lines of SF. Yeah, for me it's a cause. I don't want to one day find that the only thing available is an arcade game for Nintendo.
OK, sermon over, he he. You can go home now. :-)
