I just spent the better part of the last month sitting at a bedside, my wife and children at home, with a whole lot of time just... waiting for the inevitable, I played my switch solidly for the first few days as myself and my siblings all took turns being at that beside and enduring the suffering. But, as I "caught up" with my backlog of Switch games, I found myself wishing that I had a new vita or at least more of the games that I really enjoyed coming back to, which as it turns out, isn't Nintendo games. Before long I just stopped bringing it to the hospital/hospice center every day and would just save the gaming until my brother and I got back to his place so we could fire up the PS4, and play the games we liked to play together, I am completely done with Splatoon 2, Mario Odyssey, Zelda, Kirby, Doom, Bayonetta, and Mario + Rabbids. I've never been a Smash or Pokemon fan, and I have no interest in picking up third party titles I've already played, and beaten months if not years ago on other platforms, and I just don't know what's left for me. My Switch is slowly but surely becoming nothing more than the neat thing that gets played at friend gatherings and little more. Sure, Mario Kart 8 and Mario Party are the same laughs they've been for 20 years (and to be honest not much has changed vs theier Wii counterparts). Mario Tennis Aces has shown that it's gameplay is increasingly grating as the key to success is mastering gimmicks rather than tennis itself. So here I am, looking at Zelda: Link's Awakening and Grid: Autosport and thinking "I guess so since there's really nothing else".
I used to bring my vita everywhere and never ran out of something to play for years and years. There was always something else to keep my going, or something compelling to keep me going back to. The more time goes on, the more confident I am that if Sony announced a new portable tomorrow with say, PS4 digital compatibility, my Switch would quickly go up on craigslist, and probably wouldn't be missed.
Side note: Pick up Super Mega Baseball 2 if you can. Super solid game, but, unsurprisingly, not available on Switch.
