It is a shame that many people look at the graphics and don't see the quality of the game 'from the outside store window'.
Compared to the games of this generation I can easily see how many are turned off by the dated graphics. I can also see how many are turned off by the more challenging gameplay also. Many games of this generation (if not all of them) are made to make the player feel "badass" where you slaughter supposedly trained enemy soldiers and come out on top. All while being able to tell if they have zits on their faces or not.
Personally, I am not concerned of graphics, but the quality of the game. There are many games out there that have nice graphics but poor or limited gameplay. I value the quality or the heart of the game over graphics any day. However, to see HTC work on the terrain the way they are now, I am excited to see what the final outcome will be when it's all finished.
I think the biggest turn off to new players though (if they walk in the door), is the flight model. It is challenging, and many who play games to be 'badass' don't like challenging. At least not on the scale that HTC offers, where it takes years to be good. However, I would rather play a game like this where you actually need to know what you are doing. Rather than playing Call of Duty and "quickscoping" other players knowing where they most common paths are taken, and calling that skillz.
HTC has kept me here for 6 years. I'd say they are doing something right
