Back when Pokemon Red first came out, on paper it seemed like a game I would enjoy. I borrowed a friends copy and attempted to play it. I say attempted because I got to the second or maybe third town before I gave up on the game. It was tedious and boring as shit to me. Based on that experience, I avoided subsequent Pokemon games since, as far as I could tell, there weren't any meaningful changes to the formula that would cause me to change my opinion of the series.
Fast forward to November 22nd when I purchased the Zelda 3DSXL bundle. A friend of mine had been pestering me to try playing the new Pokemon game since I was getting a 3DS for the first time, so I picked up Pokemon Y when I picked up my bundle (along with a couple other games, but those aren't important.) I can't put my finger on what they changed that made this new game catch and keep my attention, but I have now beaten 6 of 8 gyms, and am just under 2/3s the way through completing the Pokedex. I dare say I am actually enjoying this game.
There are several changes that happened between Red and Y beyond the obvious graphical improvements. Experience Share is probably the main thing that has helped my enjoyment of the game; not having to switch out my pokemon to get them to level up gets rid of the majority of the tedium I felt in Red. The roller skates are a pro and a con to me. Yes they allow you to travel faster before you get the bike, but I feel that the accuracy of your movement is hindered by such.
There is one thing that I really just don't care for in Pokemon Y though. The camera in Lumiose CIty is too fucking close and too low when you aren't riding the bike. I understand what they were going for, but their execution of it is piss poor. I've heard people call Lumiose a nightmare to navigate, I wouldn't go that far, but is definitely annoying since you don't have camera control.
All in all I won't let my dislike of Lumiose hamper my enjoyment of Pokemon Y, it is a rather enjoyable experience. Does this mean I'll be picking up the next Pokemon game? Probably not, and I almost certainly won't be going back to play the older games, but my opinion of the series has definitely improved. I also kinda understand why people clamor for a Pokemon MMO, but I seriously doubt that will ever happen.
One final thought: Fairy Tale Girl looks high as fuck.
