I recommend you to look forward for the pokes to have fun, but not for the movesets or natures, nor evs.
As you are beginning, you won't have access to all moves, since TMs/Tutors lf some of them, are in other regions. Also, keep in mind that this game has the mechanics and movesets updated as to gen 7, so blastoise, for exampld, doesn't learn shell smash.
Lastly, in order to get the correct nature/ev, you'll have to spend plenty of time/money to train them as you want. I did it, lol, but people called me crazy for doing it. If you want to do it, go ahead, but you might not find the grinding for correct nature/evs part so nice. :]
