Never have boxed mine, though I did force my Pikichu to evolve in Yellow twice. But generally I'm not disapointed in my starter, outside of Tripig. Man his evolution was mostly worthless and vowed never to train one again.
For some reason I just beat the whole game with the starter, and everyone else is just there to revive the main guy, which worked in diamond, starly and turtwig = staraptor pretty much killed everyone.
In black Im not so lucky, I got that fire pig and im stuck after the elite 4 xD
Almost always. Aside from Charizard and the Gen 4 starters I have found most others to be too stuck on one type. Pure grass type is insta crap to me, pure fire isn't that great either and most of the fighting ones don't have access to basic good fighting attacks. Finally water types are quite nice, but there are so many good ones in the wild. Lapras, Lanturn, King Jellicient, Starmie.
