The New Super Mario Bros series has generally gotten better over time. the 3DS and Wii U entries are far better than their DS and Wii counterparts.
Final Fantasy 4 is the best entry in the main series.
Half-Life 2 is not that impressive nowadays, especially compared to Valve's other games.
Mario Kart 8 had a better Battle Mode than any entry in the series since Double Dash or so.
Resident Evil was only good for a brief period of time on the GameCube. The 5th gen games, which supposedly revolutionized horror in games, was both predated by a number of other horror games like Alone in the Dark, Clock Tower, and Capcom's own Sweet Home. Horror games released after the first Resident Evil often surpassed it, especially Silent Hill 2. RE5 and RE6 likewise are infeior to third-person shooters both before 2008 and after them. RE4 is the only main entry to stand the test of time.
"Metroidvania" is a terrible name for the genre. Symphony of the Night, which was responsible for the second half of the name, came out a decade later than Metroid and sold far less copies. It would be like naming the FPS genre "Halostein" or something.
The "Tidus Laughing" Scene from Final Fantasy X was one of the best parts of the game, and one of the few where the voice acting was truly on the mark.
The Super Smash Bros series has often done a bad job choosing which characters to include and how to represent them.
- In the original, Ness should not have had access tO moves like PK Fire or PK Thunder, seeing as he was more of a Fighter/Healer in his original game. Captain Falcon should not have been included, seeing as he was not exactly a prolific character in even his home series.
- Melee did a poor job with new Zelda characters. Though Zelda's Sheik form was not necessarily a bad idea, it made her hard to associate with games other than Ocarina of Time. Furthermore, her abilities show little resemblance to their original forms in her home series. Din's Fire was originally a close ranged attack, not a projectile. Her slow speed makes little sense considering how she is literally Sheik. Her lack of Light Arrows is also bizzare. Speaking of this series, Ganondorf was a mess. In his home series, he was most likely to use either swords, magic, or perhaps a trident. Why does he rely on his fists then? If you had to make him a clone, at least make him a Marth clone so his weapon is more appropriate. Or skip Ganondorf and use Ganon as a Bowser clone.
- Brawl improved some characters, but also made some mistakes. Wolf may not have been a complete clone, but was still not a good choice considering how Star Fox was largely irrelevant even at the time. If anything, not being a clone means Wolf possibly came at the expense of another character. Snake may have been the original 3rd party fighter, but his lack of guns felt like Link without a sword; inappropriate. Lucas came from a great game, but added little to the roster either in terms of popularity or gameplay diversity. His use of offensive PK abilities rather than healing ones was even more egregious than it was with Ness.
- In SSB4, Lucina is ridiculously similar to Marth, even by clone standards. At very least, she could have borrowed Robin's Final Smash, much like how Dark Pit borrowed his from Zelda instead of Pit. And maybe some of her alternate special moves could have been her default to help differentiate herself? Assault Dash could replace Shield Breaker, Effortless Blade can replace Dancing Blade, her counter could have different properties, and so on.
