Yeah I'm more in for the plastic figures of fave characters than the gameplay opportunities.I can see myself just picking up some of my favorites (Sheik, Marth, Fox), but this E3 really hasn't sold me on these things at all from a gameplay perspective.
I'll probably scan them into Smash 4 once just for shits and giggles... then onto the bookshelf they'll go.
Yoshi, AC Villager (male and female), Pikachu, and Kirby for me. Maybe more once non-Smash figures get released.
