So I got the game today (cause Europe, but the local store sold it a day early) and I've been playing for a couple of hours now. Most of this time was spend hunting wild Pokémon on Route 103. So far, I've mostly leveled up my DexNev abilities (Hordes are especially helpful, combined with a Sweet Scent Lotad) and my best catch so far is a shiny Zigzagoon with Tickle. Still trying to find that perfect Ralts to eventually evolve into a Gardevoir
The exclamation points are super helpful as well
And last but not least, you don't have to catch/breed countless Pokémon anymore to get something really good (something I always feel a bit guilty about, I know, it's weird XD)
I better go back to playing the game now, cause I still got a lot to discover!
