Ooh, fun! Let me try. Feel free to argue with me, I'm happy to be proven wrong.
Donkey Kong Country: Tropical Freeze is astonishingly overrated. While it's got some clever moments of aesthetics tying to gameplay, it's largely a homogenous chore to play. The swimming is dreadful, the theming of the worlds is so strict that they get old after three stages, the multiple playable characters, while welcome fanservice, are basically redundant besides Dixie who is the best in almost every situation. It's by no means a bad game, but it's brimming with odd decisions, such as that rocket barrel stage with the awkward 3/4 isometric-style view that just makes the obstacles harder to parse. Best 2D platformer ever? It's not even the best 2D platformer in the series.
I vastly prefer the more modern action-focused Resident Evil titles to the legacy fixed-camera ones. My favourite in the series is Revelations 2, which is a masterful co-op game married to a deeply compulsive Raid mode experience. I've pummelled hours and hours into it.
Super Mario World is utterly tiresome by comparison with Super Mario Bros 3. Again, it's not a bad game - in fact, it's very good indeed - but it's so easy you can breeze through it barely paying attention, and replaying levels for the secret exits just feels like tedious padding. Aesthetically it's also very unappealing, like some hi-res DOS platformer.
Sonic Forces is the best 3D Sonic by a wide margin. The bite-size levels go a long way toward making the game compulsive, it runs smooth as silk and is more or less glitch-free compared with the other entries in the series. It's the only one with a consistency to its gameplay and it holds up well from beginning to end, with plenty to do post-game, too.
The Mega Man X series is mostly bad. X3 through X7 are wretched (though I have an odd soft spot for X5) and X2 ain't so hot either. X1 and X8 are the only essentials, the former being a masterpiece and the latter being a genuinely interesting take on the series tropes. Mighty No. 9 is probably the third best X game.
Super Mario 64 sucks, it always sucked and it will suck forever. There are fundamental problems with the gameplay structure that prevent it being any fun whatsoever for me. Every 3D Mario bettered it.
Breath of the Wild may have some fun buried in there somewhere, but hell if I could find it.
Soulsborne games are not as difficult as everyone tends to make out. Exept for Dark Souls II, fuck that game.
The best Paper Mario games are Sticker Star and Colour Splash, by virtue of being full-fledged exploration adventure games, rather than half-assed JRPGs. Thousand Year Door, while definitely not bad, has several sustained chapters that are entirely uninteresting in gameplay terms. Having said that I'd buy it again on Switch VC in a flash.
Rogue Legacy is absolute ass once you get over the initial drip-feed of meaningful character progression. Looks and feels cheap.
Horizon: Zero Dawn put me to sleep. Deeply dull opening and overfamiliar narrative meant I didn't feel inclined to give it my time.
Ubisoft are a fantastic and consistent developer and I'm almost guaranteed a good time when I pick up one of their games. Exceptions exist but are very minor and very much the outliers.
The Wii U is and was an absolute pile of garbage. Great (if small) software library, but absolute garbage hardware, UI and experience. The Wii, however, was a glorious wonder of amazingly diverse and plentiful games; somehow underrated despite selling infinity jillion systems.
All my gaming opinions are subject to change at a moment's notice. I make a point of revisiting games I dislike to see how I feel about them now, and often find myself pleasantly surprised.
