This here features every httyd related non School of dragons game I could find. Some playable some lost to time. Apologies in advance if I sound a bit too mean or rude in my reviews.
Console games:
How to Train Your Dragon(WII/PS3/XBOX 360,Nintendo DS)And another one I can't review bc it's only avaliable on xbox 360 in my library system:(
Dragons:Dawn of New Riders(XBOX One/Nintendo Switch/PS4)
Mobile apps(excluding SOD)
lost/defunked forum games hosted by Cartoon network(I'm using the httyd wiki so IDk how true this stuff is since I mainly played SOD back when you used timberjacks to fly around so I'm not really a relabile source but I don't know why a wiki page for forum games would lie about mundane games)
