I am Setsuna? Neo Geo ports? Shovel Knight? all neat games, none of them "essentials". Zelda and Mario Kart, very much so.
Guess my point is more or less that with the lack of titles for the system damn near everything has to be essential.
Didn't know tlou wound up on there but then again I don't tend to follow re-reviews for games already deemed great and goty
It's just that - seeing as the Switch is likely going to reach a (way) higher installbase than the Wii U - there'll be a great number of players who haven't had access to the original version, MK8 deluxe is an essential game to own.
Also, the Switch is not only the successor to the Wii U, but also in part to the 3DS (even though Nintendo's still too coy about that - but for me that is 100% the case, it's already my 'play in bed handheld' of choice), and if you look at the generational leap from Mario Kart 7 on the 3DS to MK8D on the Switch (just check the DF video), you'll understand just how essential this game is.
