Sigh...Alright, I'm gonna speak my mind.
First things first - the names. Snivy, Tepig, and Oshawott - are they really worse or less creative sounding than Squirtle, Grimer, or Magnemite? No, they're not. You people cannot really mean that you think that "Grimer" is a better name than "Oshawott"? Maybe it is, because it only takes 1 second to understand. These names (spare Snivy) actually have a little bit deeper of a meaning. You can't just glance at them and know what they're talking about. Anyways, I'm droning on - if you guys really don't like their new names, for the love of Giygas, just nickname them! You are given the option to, you know.
Now, about Unova - it seems a lot of people dislike that name because "HOMG THEY DID SOMETAN DIFFERNT DERP DATZ BADD!!1". Oh, quit whining, just because something is different does not mean it's bad. I admit, I at first thought it was a little odd, but after I found out what it possibly stood for, it sounded a lot better. Different, but better. Sometimes, guys, change is a good thing - It means they are really trying something new with this gen (or are at least attempting to).
In other words, just relax - no one's forcing you to say these names and no one's forcing you to like them. I'm all for opinions, but when everyone starts to sound like cranky 7 year-olds, those "opinions" sound a lot more like a case of butthurt. If you don't like them, quit raging and get over it. Seriously. These names will not change, no matter how much you cry about them.
(Wow, I think that was a little unnecessary.)
