I feel the SMSB thread has been really fun because we all have a shared vision. We all know what games we want represented, and we all know what characters fit in or don't.
The closest thing to a worry about overrep/bias we have is I guess either between Wario; DK; and Yoshi, or between WarioWare and Wario Land, and even then I think we've done good on the prior (a little in DK's favour, but DK is a much bigger series than both in terms of popularity and game quantity so it's understandable) so far and it's too early to say if Wario Land will completely overshadowed.
