I can name a few reasons why I won't play your game.
I don't care. Seriously, I don't. Nor should you or anyone else aspiring to make a game.
(And no, that's not a passive aggressive smiley.)
If we look at the odds rationally, most of us should give up now. There are plenty more rewarding ways to spend our time, depending on how you measure rewarding (especially if you measure it in terms of keeping a roof over your head.) We're in the era of extreme media segmentation.
There's niche upon niche upon niche. Nobody has time, we're told. Games compete with every other form of entertainment and only a handful of people succeed.
The sterile logic of business seems to suggest dumbing down. Mass market. Get bigger. Eye candy, voice over, cinematic scripting. Painstaking, expensive, typically non-replayable. Nevermind that it's unsustainable. Maybe microtransactions or reskinning and selling the same game or massively multiplayer treadmills through repetitive, meaningless worlds will save us.
Or not.
It doesn't matter. I mean, sure, to those footing a mortgage or paying a prince's ransom for some square footage in an office I'm sure it matters a great deal. But to most of us, probably not. Maybe we will make the next Angry Bird or Minecraft and hit the jackpot of fame and fortune, or maybe we'll grow into the next Zynga or King and capture some market segment while burning the earth behind us so nobody like us can follow.
Chances are non of those things will happen.
If that's the case, then how would you have liked to have spent your time? Desperately fretting about factors created by the insane glut of games that are thoroughly beyond your control? Or having fun using your limited time on this earth making something you love, even if you fail and nobody ever played it?
Strategically speaking, it just seems to me that one approach will get you a guaranteed outcome with positive results. The other's quite iffy.
And speaking of guaranteed outcomes, of the many things you'll do in this life, some good, some bad, most average and forgettable-- until the advent of more advanced technology, you will most assuredly die. Rather than being morbid, that fact should be inspiring. Even if you have 100 years left, it's not enough time, and certainly not worth it twisting yourself into knots worrying about what this or that changing taste will like. Make what you can make, and enjoy the process. And if you can stand it, do it again.
(tl;dr version: You're gonna die no matter what you do, so make your damn game and have fun doing it!)
