Some examples of game logos that I like. There are some 3D and 2D logos here

This is the retro pixel art style, these examples show it in a very retro old style way and also in a very modern more detailed way.

The classic game space invaders was pixel art so by making Rocket Rampage pixel art style it could give a nostalgic feeling to it relating back to its space game past of space invaders.

However by making it pixel art I don’t want it to look like too similar to space invaders, I want to give it its own unique look and style.

Chucklefish games

chucklefish games have a unique pixel art look, they have created a modern style twist to the pixel style look. Using very small pixels they make their visuals more detailed and also using shading to add detail. I really love the visual look of all there games.

A link to a website that supplies free materials for c4d, I used some of these in my logo design roughs for the game.
