>>11197687There are two problems. One is that you need to make concessions to the look if you want full articulation, The other is that Bandai is simply afraid to push things too far. Their "retro" RX-78-2s, like the Ver. A.N.I.M.E. RD or MG 2.0, don't do nearly enough to mimic the vintage style, they adopt a few of the aesthetic details and slap it onto a relatively modern-looking template. The Best Mecha Collection one is probably your best bet.
Actually, a third problem: "anime accurate" is tough here because 0079 was so frequently off-model.
