It might be obvious but I was thinking about all of the IL-2 videos that now inhabit YouTube. We have machinema style movies/movie trailers up there, videos of silly things happening, of someones first kill, competitive 1 v 1 dogfights, and videos of virtual aerobatics teams that are very professional looking.
And if you start reading some of the comments from people they seem to always be saying "Wow! That looks like a really good game! Where can I get it?" It seems like IL-2 is a total unknown outside of the typical sim community, BUT, all of these videos seem to have people interested. I wonder how many sales of the game have happened in the last couple of years since YouTube got popular? Especially to people who are traditionally NOT flight simmers.
If anything this suggests the power of fan made videos/machinema as both an artform and as a marketing tool.
If there is anything that Storm of War needs to give us...its more power over camera controls. I'm sure the video makers would love to have visuals that are nearly impossible right now and it'll create some impressive looking shots that will market the game beyond any one advertising budget. Its good for us as they will keep making sims so long as the cost/audience works out
