What does a "grounded" skin in COD mean to you?

For me it's the following:

1. If it's a historical or modern COD, all the skins should be human. If it's a future COD, depending on how far in the future the setting is, it can include robots.

2. All skins should be military or civilian themed. No wizards, superheroes, or shit like that.

3. No celebrities!

4. All guns and ammunition should be designed to fit the setting of the game. Lasers should only be allowed in games that take place far in the future. No unicorn guns, or guns that shoot weird fantasy shit!

5. No death animations where people turn into random shit when killed!
