Worth buying a Switch for? Last Nintendo console I had was the Gamecube and I did not do much with it. Really thinking of getting the Switch but find it hard to justify the purchase because of the high cost, especially in comparison to the PS4 and Xbox One
It depends. You're right about one thing, you're definitely going to be paying the Nintendo tax if you take the plunge. Big name titles on PS4 or Xbone could go from $60 to $20 in just a couple of months, but when Mario and Zelda come out on a Nintendo Platform they debut at $60 and stay there. There is also the question of memory. I get physical releases from Best Buy for the GCU discount, but if you buy digital you're going to have to invest in an additional memory card.
You'll also want a carry bag for your Switch ($10-20) a glass screen protector ($8). While those purchases are pretty much mandatory, you will also at least feel inclined to invest in a portable battery pack ($25+) and a USB C Cable and AC that you can take with you in your bag and charge on the go. ($35) It all definitely adds up.
On the plus side if you haven't owned a Nintendo system since Gamecube, that Wii U titles like Mario Kart and Breath of the Wild will be fresh for you and are must haves. Mario Odyssey is as well, with Xenoblade Chronicles slated for next month and this is just the first year of release. It definitely has the games, but you'll be paying for the privileged of playing them, make no mistake. If you're on the move a lot and the portable nature of the system could really benefit you, I think it's worth it. If it's just going to sit docked at home all the time and you're not going to have friends over regularly to play Mario Kart and Smash Bros. however, you could possibly pass.
