I know the feeling exactly. The sad truth is that most people don't want to be marketed to, even if they would genuinely enjoy the product. That's how I see it anyways. I'm stuck between wanting to be invisible online and wanting people to play my stuff, which makes it hard to put myself out there to sell a product.
Viewing post in Marketing is hard, huh?
This is where I suspect a lot of us are. Game devs are fairly solitary creatures who do not feel comfortable pushing their games onto others like a common huckster. Marketing requires a certain abrasiveness. You need an aggressive personality, and nothing turns me off more. I'm far less likely to try a game that's been shoved in my face than one I happen to stumble upon. It's sad that marketing is even necessary. Coding, graphic design, etc is hard enough without having to learn yet ANOTHER skill.
This is largely how I feel. I make games because I want to make them, but I still hope other people will play and enjoy them. I just don't have much of a stomach for self-promotion. It feels tacky, presumptuous, and embarrassing. I share my work in some limited circumstances but "marketing" as such is not really something I do. Fortunately this is just a hobby for me and not my livelihood.
One thing that stops me from sharing as much on this board is that my current "flagship" title is fairly niche and requires several hours to complete. I feel that it's not really compatible with the video impressions and open feedback threads here.
