Emerald was the first game that I really got into, and I have a lot of nostalgia for it. I put over 800 hours on that little save file, IIRC. I had caught every Hoenn Pokemon except Milotic. I got Feebas, but I just couldn't seem to ever manage to get the Pokeblocks right for the evolution. I had a lot of fun with the cloning glitch at the Battle Tower. I've been replaying with a randomizer lately, that's been a lot of fun and I very much recommend it. It's fun to adapt and not fall back on the same strategies that I always use, you know?
