Well, then it has the potential for success with some people that are happy with a 4 month time window and a handful of planes flying all kinds of missions, but you seem to fail to realize that no matter how many maps or alterations you make you are still constrained with 8 planes between late-42 and mid-43 in the stock version. In reality, this mean that we can make a million maps and as many alterations as we humanly can but we are still limited to Germany and the USSR with 8 planes flying over the Eastern front between November 1942 and February 1943. One can't step outside those boundaries with new planes or the ability to mod the existing planes, which the dev's have said we can't do.
You do have to realize that it will constraint modding. What if you want to make a Barbarossa scenario? You can't if you dont want to make it very silly and anachronistic with planes from 1942 and 43 flying a Barbarossa mission set in 1941. What about the Battle of Kursk? Operation Bagration? Siege of Leningrad? Battle of the Crimea? Missions set in 1944, 1945 with only planes from 1942 - early 43? BoS is fine if i am happy with those constraints, but i am not. I want barbarossa, Crimea and the battle for berlin, and thus BoS will not be the ultimate game for me.
These are modding limits. Given the unmoddable set of planes, unability to add new ones we can't fly missions outside of the fixed timeframe of late '42 to mid '43 and that will hamper it's success with us who are interested in more than just 8 planes from 2 countries flying during 4 months of the Stalingrad campaign.
So, in a sense BoS has the potential for great success as well as it has the potential for horrible failure. For me, it all depends on how much the game will be supported in the future and if we will get new content to use. Believe me, very few people are going to stick with this game for 10 years if there won't be more than a handful of planes and such a narrow scope as it has now. I, for one, likes variation and i would surely have fun with BoS for a while, but sooner or later i will get fed up with 8 planes and the lack of variation and move on. Part of what makes 1946 stand the test of time the way it does is the fact that thanks to mods we can fly everything from WW1 era Fokkers and Nieuports battling over the western front with flimsy machine guns in 1916 to MiG 17's and Thunderjets duking it out with heat seeking missiles over Korea in 1956.
The best part of it? I can choose without limits whatever i want. 1946 is like a big candyshop where i can choose whatever i want from hundreds of boxes and enjoy it.
With BoS i can choose but only within with very sharp limits and timeframes. It's like being in the same huge candyshop but restricted to one or 2 boxes among hundreds.
