Your comment would've made more sense if Snake was actually owned by Sony.
Not iconic for Playstation?

Nintendo - 3 remakes main releases, 1 exclusive side release.
XBox - 2 original main release, 2 remake main releases, 1 original side release, 1 remake side release.
Playstation - 4 exclusive original main releases, 1 non-exclusive original main release, 1 remake main release, 4 exclusive original side releases, 1 non-exclusive original side release.
Or, if that isn't clear enough, let's put it a simpler way.
Nintendo has 4 titles....3 or them remakes.
XBox has 6 titles....3 of them remakes.
Playstation has 11 titles...1 of them a remake.
It has been (nearly) exclusive for Playstation for original releases, but recently there have been some combo packages with old games for new systems. With the newest games, XBox is getting thrown into the mix, as other games like Final Fantasy have started doing as well. Nintendo isn't even getting MGS5 - they only get occasional remakes. The one game Playstation never got was a handheld game that came out before PSP existed.
Anyone who has followed this series would unquestionably associate it with Playstation.
