We weren't here first?
there are many other companies that go by the idea that they make games that everybody can enjoy, but they do target a specific audience with each title they put out.
Rare Ltd.
new logo old logo
rare are a british games development company based in Lancashire, England,
it was originally founded in 1985 and for the most part, worked under nintendo creating classic games such as; Banjo-kazooie , Donkey kong country, the revolutionary Goldeneye 007 on the nintendo 64 and even the hilarious, yet crude, Conker series.
they have since, left work for Nintendo and do a lot more for Microsoft though they have done some things on the current formats.
as you can already tell, they have a large variation of genres they are juggling there, with the FPS of golden eye and the cartoon-ness of donkey kong it's hard to pin them to a particular target audience, even though the vast majority of their games are more structured for 10-13 year olds.
because they have a large variation of productions their logos are actually pretty simple, consisting of a shape that resembles the outer curve of the letter R, for rare.
this is a very neutral seeming design and it is effective in allowing them freedom to produce what they can, without having to stick with a sort of style.
(it's worth pointing out here that some companies that do the multiple genre thing tend to re stylize their logo depending on the game they are making, though their main logo stays the same.)
PopCap Games
popcap's logo
Popcap games are an america video games developer and publisher in seattle, washington, owned by the dark and evil overlord of games EA.
Popcap are a developer of the more casulized game, such as Bejewled, Peggle, plants vs zombies and feeding frenzy.
because of how simple and casual their games are, they have a large market they can expand into, as they don't really have to worry about who plays it, because pretty much anyone picks these up and gives them a try, from kids on their mothers phones, to grandparents having fun on the web.
so because they have such a vast pool of potential customers, they have to keep up a company image, so that merits the smooth and friendly logo they have, it clearly shows who they are, and to some extent gives you a feel of what sort of games they make.
Team Ninja
Team NINJA's logo
team ninja is not like the other two examples.
team ninja doesn't take S*** from anybody, they play by their rules and their time, and they have a bad ass looking logo to prove that.
Team ninja was founded in 1995 by members of techmo specifically for creating home versions of the fighting game Dead or Alive 1 & 2
when that went over well they created a 3d version of Ninja Gaiden, a hard as nails game that is part of the main series originally beginning back on the NES.
because of their heady combat based gameplay, and graphical feature dubbed "jiggle physics"
their games are far from being children's games and more for adolescents from the age of 16+ (probably from age 17-19 as a target audience).
their logo can easily reflect this, as it doesn't look like a logo you would find on something like a kirby game.
