Most recently played Pokémon game?

[Nylon]

I played through Uranium for the seventh time not long ago... I do different teams every time, maybe trading over pokemon like Minicorn and Slothohm so that I may use them throughout the adventure, When I complete the game I trade the pokemon to a specific file where I store them so that I can look at all the different teams and remember how well they did and how surprisingly useful some of them were. I love collecting and I very much enjoyed Uranium.
 My last adventure I used (in order of acquisition (all pre-caught in and traded from another file)):
-Minicorn (Oblivicorn
-Linkite
-Frynai
-Selkid
-Sheebit
-Xenogen (evolved upon arrival to Xenoqueen)

I love them all very much, and after experiencing Xenogen have opened my heart more to other nuclear types that aren't Nucleon. I also want to remind everyone that Chainite is such a cool pokemon even though they have the devastating lack of Sucker Punch.
 Have a nice day, anyway.

Prior to Uranium? XD Gale of Darkness. It and Colosseum were the last new games I played in the series. I just got sick of the unecessary complexities, the abandonment of the double-battle focused gameplay of the Gamecube games, the utterly throwaway "stories" and all the little irritations that just mound up from game to game.

I started playing Uranium because I didn't need a glossary of 6 million goddamn mons, there weren't multiple versions that said "lol, can't catch 'em all because version exclusives bitch!", no "lol, you bought the game? Dumbass, here's the *real* game!" (Yellow version, Crystal, Emerald, etc.), no "Oh, you want to evolve that pokemon? Too fucking bad! You have to trade with someone else and hope to Christ that they have some measure of honor, or buy another system and copy of the game lul!", and no "Oh you want this legendary pokemon? Well fuck you! It was a temporary event, you missed it, and now it's gone forever!"
