Also, there's no way to do a G1 Transformers unless you're making an 80's period piece. The reason they were blocky were not only because they were the first, it's also to do with the vehicles they were originally.
War for Cybertron
This is a modern game, and while it does borrow slightly from the Michael Bay movies, the robots all look distinctive and most of them atleast have faces. I would have found the films more enjoyable had they gone with designs closer to this.
The cartoons were good because all the transformers were visually distinctive from one another and had different personalities.
In the Michael Bay films I can't really tell who's who cause they all look like mecha's from Neon Genesis Evangelion, after getting put through some kind of giant machine shredder and they pasted together haphazardly.
Only a few Transformers like Prime, and Bumblebee really stick out.
