Kind of wanted to go more in-depth in my post, and I'm actually wondering if anyone else feels the same way. Here goes!
Well, think about this guys: what about having a permanent companion of some sort? Think Pokemon Colosseum, where you (as Wes) play with a partner (Rui). Would you want the games to be something reflecting this, or would you rather have this as more of an optional feature?
For me, I'd think it'd serve as an interesting mix having some sort of a permanent partner, but only if you can choose who it can be. It's a pretty iffy double-edged sword, if I do say so myself, and I don't think it's too overly necessary, though it could help to change how Gym/Elite Four battles are done. What do you rest of you guys think?
