There may be a significant representation of ports on that list, but they're mostly ports of franchises that can have a real strong evergreen effect across a system's entire lifespan: Mario Kart, Smash, Pokemon, Splatoon.
I've always like the idea of getting these types of games out early in a system's lifespan because they're just the sorts of titles that are instantly essential, so every new Switch owner ever will probably give these titles serious consideration as to whether to buy or rebuy them.
Additionally, I'm hoping that not having to worry so hard about delivering a "Mario Kart" franchise on the system means that Nintendo's dev teams can move onto new and different and compelling things sooner rather than later.
Plus these are simply just strong names to have at the ready when going out to market the switch.
Now while I'd be less than enthused seeing a lineup of ports on a new console, that list also shows a new Mario, a new Zelda, and a new Pikmin. That's exciting to me no matter which way I slice it. Plus I'm hoping that the third party offerings, slim though they are guaranteed to be on a Nintendo system, are compelling. I've never played Skyrim, I'm definitely game for a Mario Rabbids RPG, I'm decided on Just Dance 2017, sounds like I'm going to get a Basketball game... and is that a Telltale game I see?
I'm starting to worry that if Year one is this awesome, year two can't be anything but disappointment. Maybe Switch year 2 will actually get some original IP from Nintendo First Party?
