These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Everything TerryBogardsays. It's to the point where that fact in itself is becoming a meme.
Never Live It Down - Unfortunately, the Capcom/SNK rivalry of the 1990s (see Follow the Leader on the main page) often slips into downright denial that SNK ever actually came up with something on their own. This is made even worse by the fact that while SNK and Capcom did crib off of each other time and time again (and face it: particularly everyone did this), several fighting game mechanics could be instead attributed to SNK.
Polished Port - Nearly all of SNK's ports (yes, even the Game Boy and Neo Geo Pocket ones) feature this to varying extents. At the very least, expect nearly arcade perfect gameplay, secret characters not found in the original arcade releases, artwork galleries, and maybe a few extra gameplay modes. The PS1 ports of most of SNK's '90s line-up featured fully-animated intros and the option to play the AST themes as opposed to the OST ones. The Dreamcast ports of The King of Fighters '98 and The King of Fighters '99 (The King of Fighters: Dream Match 1999 and The King of Fighters '99: Evolution) had most of the aforementioned bells and whistles. Arguably, Neo Geo CD owners had it the best; for example, KOF '96 received an upgraded port known as The King of Fighters '96 Neo Geo Collection. The game included, among other things, character profiles spoken by the voice actors themselves, a reenactment of the game's backstory, a sound test, and outtakes.
