Here are my opinions, in no particular order... I'd love to hear what other people think of them, but please, no bashing.
So first off: Fairy type.
At first when the rumour was going around, I thought "no way they'd EVER do that" but as I thought about it more, I began to like the idea of it...They will be good for counteracting dragons, and, if the rest of the rumours are true and they are weak against poison and steel, it seems that we have good enough reason to bring those types into online play.
I also love the idea of switching older pokemon type. Seems a bit silly that jigglypuff can now kick my garchomp's ass, but hey, whatever, I'm not complaining.
My guess is that perhaps dunsparce will get some kind of fairy evolution. He's been around since gen 2, there is NOTHING special about him, and he has wings... Why not give him a really cool evolution? Or even two evolutions, one into a fairy, the other into a dragon? Who knows. I don't really like him as it is, perhaps an evolution will give him some more love from the fanbase.
Next: Vivillon
I really love the look of Vivillon. great colour scheme and apparently its wings hold a secret? the pattern on the wings kind of looks like morse code to me, I could be wrong but maybe the wing pattern changes depending on the original trainer name? I dunno, just a shot in the dark. either way, I like this pokemon and I PLAN on using it, even if it is just an early game bug type. I like its typing as well.
Next: Noivern
HOLY HELL. This guy looks awesome. I'm not sure what else to say. I don't think it'll be a swoobat evolution, but you never know. Personally, I would prefer it to just be a stand alone/new evolution line. I will have him on my team for a bit to try him out.
Next: Sylveon
Back when nobody knew her typing, I wasn't too excited about her. I didn't like the design, but now that we have the fairy type released, I am in love with her design. Her description sounds so amazing... how she wraps her bows around you as she walks with you... UGH GIVE ME ONE RIGHT NOW! I WANT ONE SO BAD!
October 12th... This makes me happy, I was expecting the release to be closer to the end of the month, which would have sucked, but this is fairly early in the month and it is a Saturday... A good day to have a release party, which I plan on hosting
Pokemon-Aime - I like the idea of this, but I really hope it isn't 100% required in order to keep your Pokemon alive/healthy. I love playing the games because I love the story and the battling, I'm not sure how much I will use this application... We will have to see!
Sky battles sound really interesting, I look forward to seeing what new mechanics they have set up for them.
Horde encounters sound really fun and are a great way to stop people from powering their way through the game. It also seems like it could be a nice way to get lots of experience.
Skrelp... If this IS the seahorse pokemon, I like it. Cool design and interesting typing choice... poison/water.
Clauncher... I LOVE this pokemon. I really like the colouring of this pokemon, plus even though I doubt it will be powerful, I love almost all of the crustacean pokemon we get every generation.
Talonflame... I'm not a big fan of the name, but w/e, that's what nicknames are for... The typing is pretty cool. flying/fire... hmmmm Charizard, is that you?
I am glad that I can import from previous games, but I wonder how early on we can do this? If it is close to the beginning, I should get training some Ralts to get them ready to be fairies!
8-direction grid is definitely a step in the right direction. I think it'll play out nicely
Them being secretive about Mewtwo's new forme(s) sounds pretty promising... perhaps it will have a second new forme afterall... I had originally doubted this, but now I'm not so sure..
Player Search System. FINALLY. This makes me so happy. I also like that it is integrated with the 3DS friend list, YAY, I DON'T NEED TO GET A FRIEND CODE FOR BOTH THE SYSTEM AND THE GAME!
We can now choose the language? Unexpected but kind of cool I guess!
I suppose that's all I can think of for now... Perhaps I'll have more to talk about in the morning from another day at E3 or CoroCoro?
