Personally, I really love this game. And yes, totally worth it to keep myself spoiler free from the new pokemon. Seeing Goodra for the first time was incredible, as was discovering the final starter evolutions, Hawlucha, Gourgeist, and the existence of Mega Gardevoir. Speaking of which, I'm overjoyed to see that Gardevoir and Togekiss, two of my favorite pokemon, are likely going to be OU viable this gen.
