i really like the 'box with arms and legs' style of many of the AC6 MT units, and the system authority/navy robots all look great as well. my main problem with the protag ACs in AC6 is the way shoulder weapons attach, they use these thin fragile looking pylons instead of attaching directly to the torso/back, it looks unwieldy and awful imo. similar with the limb/body attachment points, i feel like they sacrificed on visual design to accomodate custom builds, which is silly to me because there are less parts per manufacturer and none of the parts visually match across manufacturers. my favorite AC designs are probably from AC5 and AC Verdict Day, i love the square look and leg shields and the smaller scale and the wall-jumping. AC6 feels like a more refined AC4 with less parts/content imo, still good but i wanted some weird stuff after 5. the older AC games designs are a bit too wide-legged and rounded for my tastes, but that could be because i never got far enough to unlock many parts dabbling on emulators. i think front mission 3 mechs are cooler, for an example from a comparable console era
