Getting the game green lit would happen prior to porting to multiple platforms. Player count won't be apparent until post-launch anyway. In order to get this right, it's important to focus our efforts on PC first. That will give it the best chance.

I don't think there's any particular shortage of players that would like to play an FPS on the PC...so I wouldn't consider that a problem per se.

Historically a much smaller audience when it comes to shooters?
What the ******* hell are you smoking? Are you from bizarro-earth or something?
Console shooters are barely playable because every ****** on this entire ******* planet tries to ignore the elephant in the living room - Dual analog sticks are **** at fine aim and slower at turning.
There have been very few dev teams that actually made competent console controls for shooters. Metroid Prime comes to mind, as well as the smart pistol in Titanfall.

FPS was a sibling to RTS in terms of how it requires a mouse to be played properly. These days FPS have somehow caught on with controllers, though. And the saddest part is that there's even spectator sport FPS that are played with controllers, slow as molasses and still claimed to be "fast and furious".
I'm bewildered by the amount of people that claim that Dust is fast-paced, for example. You must have been born in 2000 or something to make that claim.

Go home, you are drunk. Many FPS don't even come out on consoles.

It's like claiming that there are more fighting game players on PC.

I get you. But we still have to get the game right on PC first. I'd rather have a game on PC and hopefully next-gen in the longrun, rather than no game at all.
