Wyrmshadow's units are above par, and no doubt, any of the great designers (Wyrmshadow, Muffins, Kinboat, Smoking Mirror, Dom Pedro II, BeBro, Ripptide, and the list goes on and on... there are a great number of you fine folks

) units surpass Firaxis' originals.
Let's face it, if a game can be modded, chances are you will find a bunch of creative and experienced 3-D 'amatuer' designers (who truly love the game and recieve no profit what so ever except the satisfaction of their work and little to show for it except hard work and constant griping by the populace of whiners and anxious users such as myself) who will take the game design to the next level.
Those folks grace these pages with their fine work, and because of folks like yourself, companies like Firaxis can extend the lifespan of interest in a game/product based partly on the hard work on non-employees.
I will not buy a PC game that cannot be modded significantly - there is no sense buying a game that forces you to go down the original designer/programmer's path - it gets boring quickly.
With that being said, however, I will agree with trying to keep all units at the Firaxis size without trying to up/down proportion units that are suppose to be bigger or smaller in real life. I find that when playing with smaller-than-Firaxis-sized units, you lose the quality of the unit, and ones that are larger-than-Firaxis-sized units generally take up too much room on the field, plus at certain angles, they block the fighting animations (especially if they are fighting in the 'north' direction).
I find people who are making mecha units and such used to have that problem, but have cut back on the over-sizing as of late.
Sincerely,
