I sure didn't make any maps targetted to kids. I don't think Piggyson and the rest of the character team made their characters unrealistic so a child could enjoy it. And I don't believe the design of the game was specifically targeted towards minors.
If GR was for kids, it would be on Gamecube with a toon shader. But it's not. It's actually quite realistic. Characters are beautifully detailed. Weaponry and other technology are mirrored from their real world counterparts. Foliage is researched to be 100% accurate to the region in which the games take place. Architecture is researched to fit the style of the region, be it Kazakhstan, Korea, Mexico City, Georgia, Cuba, etc. Enemy vehicles are also chosen based on region as well. Design knows their weapons, clip sizes, rate of fire, range, etc.
All of this attention to detail and authenticity is in Red Storm games, so I'm not quite so sure why people think the games are targeted to kids and can't appeal to an older audience, be it console or PC.
