Warriors Orochi 3 is Tecmo Koei's Super Smash Bros. Considering Nintendo's pedigree as compared to Tecmo Koei's, that statement can be seen as quite laughable, but nevertheless, Warriors Orochi 3 dabbles in the kind of crossover content usually reserved for the most prestigious companies in this industry.
Regardless, Warriors Orochi 3 asks no forgiveness for the self-congratulatory way in which it shovels cameo appearances and fan service into the player's face. For fans of the company, however, forgiveness isn't necessary.
The intellectual property of Tecmo and Koei's history may not deserve the hack-n'-slash equivalent of Super Smash Bros., but I'm glad it exists.
