I suppose I'd be a mix between a Newgenner and a Truegenner... I love all the gens, whether due to memories of playing or my favorite Pokemon. Silver was my first game, so GSC (and HGSS) make me feel happy playing them. RBY are the only games I constantly come back to, so I obviously like them quite a bit. RSE holds a lot of great memories for me since it came out during one of the most fun times of my life, and I love the music and the region as well. Also, Manectric. DP I really love due to all the memories of playing against my best friend ALL the time. I like the region a lot, too, and the route music is good. BW is fun because I like all the new features like moving sprites and triple/rotation battles, and everything looks lovely!
I love all the past gens for some reason or other, but as far as gameplay and battling go, I always prefer the newest games, because...they're just better!
