A lot of the announcements really impact you differently based on what systems you have/use obviously.
As a PC gamer, I'm excited by a lot of the indies today (that I haven't bought on PC) because I like the idea of TV/Portable for games I might normally use steam for.
Since I don't own a PS4 or Xbone, any 'big market' title to me is cool to me since I'll be able to play it now if I so desire.
Since I don't own a WiiU, any nintendo exclusive, but a port, still interests me a lot (MK8 especially).
Basically, since the last console I bought was a Wii, and nearly all the gaming I've done since is PC, the Switch is hitting a lot of good notes for me but I can see why it might not be hitting all those notes for PS4/Xbone/WiiU owners.
