So - I guess I'm confused about terminology first, so maybe you can help me better understand and then I'll be able to figure out whether something is wrong or whether the display is just confusing... ;)
I'm happy to help - I just honestly don't know that I'm fully understanding the issues... :(
Thanks for looking into this.
Lol, I knew this would not be that easy to explain with text...
1- http://www.vgchartz.com/gamedb/ Basically a blank search in the Game database.
2- Well, I call it "Switch best selling list" because games are ranked based on their total worlwide sales. In any case, the three games I mentionned do not appear here as they should.
3- Yes, Dynasty Warriors 8 indeed appears in the database as it should. The thing is when the update that did bring the first numbers for Dynasty Warriors 8 (and samurai warriors, they released the same day) went up, the two games appearing here (http://www.vgchartz.com/platform/83/nintendo-switch/) were two 3DS games (- Miracle Tunes! Game de Tune Up! Tabun!, -Cake-ya San Monogatari: Ooishii Sweets o Tsukurou!). As you can see, those two 3DS games are still in the switch list (the list mentionned in point 2) whereas Dynasty warriors and Samurai warriors are not.
Concerning point 3, it is still possible that the unexpected presence of the two 3ds games has nothing to do with the absence of the two switch games despite the chronology.
I hope I was able to explain things a bit better. Don't hesitate to ask again if not...lol
