...I think you guys are missing the point. The mechanics of Brawl weren't "either poorly replicated or ignored" - they weren't replicated at all, it's a game that stands on its own two feet with its own mechanics. It doesn't play like Smash Bros. because that was the intention.
As for the PSMove being a replica of the WiiMote, the development of Move began long before the WiiMote's, in PlayStation 2 days. You might as well go on ahead and say that the WiiMote is a Dreamcast's fishing controller copycat. People are acting as if the WiiMote was the first wand-shaped motion controller and it wasn't - those go back to Atari days.
