You can sit on your ass on your couch and play it on your tv and you can sit on your ass on a bus or a plane or a train or a rickshaw and play it. That's worth $10 more each time. You certainly shouldn't deny yourself that experience.
Sure, but at the expense of stability. I bought Pixeljunk Monsters 2 for Switch for that reason (same price BTW, as the grand majority of other cross platform games, so justifications for Overcooked are moot) but regretted it after trying the ps4 version's demo - the switch version on my TV literally made me nauseas at times because of the low framerate and, even worse, sporadic frame drops. Add in a second player (same screen! No split!) and watch it decrease even more.
We need to stop pretending every cross plat game on switch is "the same, but you get to play it on a plane!" Wolfenstein and Doom at 30 fps are not Wolfenstein and Doom, IMO. There are concessions that hav to be made for Switch versions, and that should also be taken into account she considering price.
