Here's an update of the Google Trends ranking, by averaging world/japanese results
This is a popularity comparison based on Google searches, although this isn't enough and the comparison criteria aren't always fair. Google is the most used search engine in the US, Europe and Japan (+90%), and is therefore mainly representative of searches on the web. A Google search also makes something unknown become known. Like or don't like a series have the same result to advance the series in the popular culture.
With Google Trends, it would have been easy to predict SMT/Persona, Dragon Quest and, to a lesser extent, The King of Fighters.
______
01 - Minecraft
02 - Final Fantasy / Dragon Quest / Monster Hunter / Resident Evil
03 - Overwatch / Kingdom Hearts
05 - Metal Gear > *****Yo-kai Watch*****
Note: According to Google Trends, Jibanyan is currently the most popular third-party toony animal. The last game on Switch is noted 37/40 by Famitsu, but it's difficult to interpret the PS4 port.
- Megaman / Tales / Tekken
06 - Persona / Assassin's Creed
07 - Street Fighter / UNDERTALE > Dynasty Warriors
08 - Sonic > Devil May Cry / Souls / Digimon / Tamagoshi / Halo / Story of Seasons
14 - The King of Fighters / Pac-Man / SimCity > Ace Attorney / "loose JRPG" (Phantasy Star, Disgaea, Suikoden, Ys, Mystery Dungeon) / Guilty Gear / DOOM / Puyo Puyo / Tomb Raider / Professor Layton
The rest of the ranking is this:
Project Zero > Bomberman > Castlevania > NieR > Dead or Alive > Crash Bandicoot > Bayonetta > Ōkami / SoulCalibur > Ninja Gaiden > Rayman > Momotaro Dentetsu > Virtua Fighter > Bubble Bobble > The Tower of Druaga > Shovel Knight > Ganbare Goemon / Katamari / No More Heroes > Banjo-Kazooie > Shantae.
Note: the characters of this end of list only seem possible by support of the Smash community (including the ballot). The three who became Fighters (Castlevania / Bayonetta / Banjo-Kazooie) are more or less designated as ballot choices. Ditto for the western trio appeared in Ultimate (Rayman - Shovel Knight - Shantae).
