It is simply an all around better game. Plus it a lot easier and less violent. COD is rediculously hard. Especially the online multiplayer. Obviously Splatoon is better. And COD isn't even realistic. COD is also too skill related to be a good strategy game. It is way out of it's catagory. It should be a shooter game but isn't. They lie to consumers. For all of these reasons Splatoon is very superior to COD.
Splatoon is way better for many reasons. First off, it has a lot more friendly layout and color choice, would you rather play a game based around colors like green and orange of one based around grey and black? Next, you get to use a lot more moves and things like that such as, the ink roller while on COD you only get new guns and worth less perks. Finally, Splatoon is a lot more fun, this should be obvious even to COD lovers, one reason being that not only do you get cool characters you also get a more adventurous campaign/story mode. You can also use REAL teamwork instead of just going around and shooting people. Besides COD is about to die anyways.
Spelling ridiculously must be ridiculously hard as well? It is not hard at all if you use strategy to listen and determine which loadout is best for which situation and if you have a halfway-decent reaction speed. And violence means what, exactly in this argument? Also, very superior is an awkward phrase. I would advise you to stick with 'much more superior' or simply 'superior'. Splatoon's controls are awkward. Are you seriously bringing up realism? For one, it is a game and as a heavily sci-fi based game, it is supposed to be unrealistic. It makes somewhat faster paced and better gameplay. The realism of Splatoon must be just awesome for you to say that... *does thirty seconds of research* because a game about ink-firing weapons and shape-shifting human-squids that can phase into ink but only ink of their color. So utterly realistic. While it may not be a strategy game, it does not lie to his fans. It "lies" to people who have never played the game, such as I presume you to be. Anyone who has done thirty seconds of research knows that it is a shooter game.
