[@Silverwind Blade] So I know you want mainly Macross Mecha but would it be fine to have a Gundam Mecha and just describe the Fighter and Walker forms?

No; all the mecha used by the PC's will be the same model in one or two variants. I know a lot of people won't be as fond of that, as most games like this have people creating their own machines. But it keeps it a bit closer to the idea of it being an actual military unit as part of a larger force, and also harks back to Macross too, where pilots flew/piloted the same craft. 

In the old version of GEARs it made my brain hurt trying to work out why any military organization would have upwards of 6+ different models of any kind of combat machine in service, for the same role, and in the same unit. It also didn't really accurately reflect most of the 'real robot' mecha anime the game was inspired by either.

The players' mecha in this instance of GEARs are based on the [url=https://i.pinimg.com/736x/25/91/ea/2591ea8af1d25dbbb292f043a0132b08--model-kits-macros.jpg]VF-0 Phoenix[/url] from Macross Zero for reference, as I really like the look and design of it particularly.
When this thing gets off the ground (pun not intended), I have actually written a full guide to the mecha in the GEARs universe as part of the RPG background. Because, you know... that's my kind of thing o.o 
It will look like the VF-0 and have some things in common, but will of course be based around the GEARs universe and its' technology.
