No G2s for me (they totally lack the character of all the other generations, don't like 'um, never did, never will).
I collect G1s, but there are some cool G3s out there that I wouldn't mind seeing in person. And my daughter and I play together with the G4s. And it's cool for her to have a pony generation that will hopefully be full of the same memories the G1s hold for me.
