Some further, somewhat rambling thoughts a few more weeks in.
Definitely warranted that Mario Kart 8 with all its tracks has more to offer some play styles. I'm loving Mario Kart World's more freeform style in that it is a lot of fun to simply explore and do P missions, a very nice option for cooling off after losing a 150cc on final corner of final race to a blue shell as happened to me a few times. The game knows exactly how many points it needs to screw you over by for those 1 point victories. Ever since Toad's Turnpike on N64 I always loved the real world style of tracks, also loved New Donk City, but understand that many might not like it. I love the oncoming traffic and the point to point tracks that remind me of Road Rash in a lot of ways
I'm super impressed with its visual impact on certain sections, the transitions in some of the tracks such as Rainbow Road look incredible on both the handheld mode and on my new 50inch TV that has 1300 nits with very good HDR. The blue glowing water, transition to the space station and other transitions on Rainbow Road are giving me next gen arcade game vibes. The theme music and visual extravagance of Rainbow Road feels weirdly emotional, the same was true of Mario Kart 8 on a few tracks with great music as well. There's just something magical about the overall experience. I'm also loving Nintendo at least having some next gen graphics on a new console. Some of those Mario Kart World sections in HDR hold up very well against anything. Best arcade style graphics I've ever seen.
Least expected thing for me on MKW is its rewind button, I've pressed it accidentally without knowing it existed at first, and don't want to use it in races even if you can offline.
Another bonus I've found the Switch 1 Pro controller to be just fine on Switch 2, even without chat button it's still so good I see no reason to get Switch 2 one yet, maybe ever.
The virtual console offerings for full tier are amazing as well. Soul Calibur 2 with scanlines turned off still looks amazing. Back when 3D fighting games had more visual diversity. I find that modern Street Fighter and Tekken look too similar to one another, these graphics still look incredible for a GC game, but definitely prefer without scanlines which I usually prefer for all 2D games. It actually feels a bit like a remaster that way, same for all the GC games.
Those simple GBA games are well worth a look, Wario Ware a great title to complete quickly, the Metroids, the Fire Emblems are still incredible. Freely admit to occasionally using rewind on Metroids and Fire Emblem which makes them better games overall in some ways, definitely less time consuming and frustrating. If you've never played the retro consoles you could play for years on their premium online offerings alone, shame I've played most already back in the day.
Not got DK yet as as mulling over physical or digital. I went against my long standing digital only policy for Switch 1 simply due the that physical Switch games will be a sellable asset. Maybe the last great collectable console for physical games. With many Switch cards shipping with no data on them, just codes, etc, Switch 2 may not be nearly as collectable as a retro system. I regret getting some game digitally on Wii U as they're basically dead.
Switching carts is annoying, but a good to keep on-cart data games as collectible assets. Works well for story games you might play once in a while but not so great for Mario Kart or Mario Maker type games you might play more often in shorter bursts. In hindsight actually am glad Mario Kart World was digital for us and not physical.
Though Switch 1 Pokemon games are definitely worth picking up on physical and Fire Emblems, etc, practically an investment as they almost certainly will accrue value.
