Downplaying future theme so that...

[lolroflroflcake]

you are implying by your casualization example that your poll regarding a non-casualization issue will be a sentiment that will be shared by all forums. However, this is not a casualization issue. It is sci-fi theme. There is no connection between the two. As such the sentiments may be much more widely scattered.

I would also like to point out that your since your potential marketing scheme is incredibly biased towards one particular group, you are effectively excluding everyone else since you want a complete downplay of futuristic elements in marketing. Instead of worrying about trying to attract a group of in-determinant size, focus on showing what is cool about the game. Actually showing off cool stuff about a game will attract far more people then trying to down play the sci-fi will no matter what time period it looks like its from ... super cool is its own rule after all.
