And problem here is what exactly!?

It's for kids ! We're supposed to be mature people, and play with guns and grenades.

It seems like that, problem with this game is that done have violence, blood and bad language even it's great game and everyone can enjoy it.

Curious thing, huh. I think it's funny to see people trying so hard to downplay an award, whichever it is...

Almost any Nintendo game could get a "Kids Choice Award"-thing (and they usually do) and I can't really see why it would be a bad thing, really. Most of their games are aimed at everyone, so if the game is really good, any type of award would be expected.

This "I wanna feel mature" way of thinking is very common when we're in high school, but when we get past that time of our lives, I think we should let it go, as it doesn't even make sense.

Wow, goodness. This isn't about belittling anything. I am not doing that to Ratchet and Clank. That shouldn't be done to either that nor Splatoon.. They are both great games that people of all ages can enjoy. Neither one is better than the other because of better visuals, nor because one system has greater value than the other, nor because the intended audience is different. That is what I am trying to teach you.

You enjoy and care for the Ratchet and Clank a lot series it looks, and will defend it  from anyone who tried to slander it, and that is great. So perhaps you should the consider the same for games before you try to slander them yourself. Recognize that games can be great, regardless who they may be intended for or what system it is on.
