Somewhat, yes.
I still feel bad for my Meganium, Starlant (stupid name I know), which I lost when my Gold lost its battery. :(
As for my current team, less so. Although I feel a special attachment with Frank the Gloom, who's become an inside joke among my friends, and Eff Cherry, who was created and trained to help a friend feel better. But my FireRed Pokemon still aren't "friends". Maybe it's because I've been abandoning games after beating the E4 recently, and plan on doing the same on FireRed...
