ok guys first. I FKING LOVE THIS GAME!!!
Love the idea of it, I love how strategic it is. However, I do feel like it's lacking a sense of punchiness that can make it unique. SUP com had plenty of units that had unique traits that were over the top and set them aside from the other units. For this game, I would like to see something similar.
My suggestion: Giant Walker units like Universe at War:
