Something I started a loooong time ago, but just recently finished: a set of brushes and symbols for each of the franchises represented in Super Smash Bros. Brawl!
I actually made another version of these prior to Brawl's release, back before I even knew anything about Illustrator, which can be found here: [link]
Anyway, those sucked, so I decided after being introduced to Illustrator to make some new ones that were nice and clean. And here they are! Included are 23 different icons, one for every character and franchise represented in the game.
Photoshop: copy the .abr file over to Photoshop>Presets>Brushes.
Illustrator: copy the .ai file to Illustrator>Presets>Symbols.
Simple! And of course, the symbols and logos used are © their respective owners.
