I enjoyed playing old Ruby and FireRed a long time ago. I was owning the Elite Four hundreds of times. I knew about the elusive shiny Pokemon and all the rumors about them. I thought I was the Pokemon Master. (I think I completed the Hoenn Dex even.) But when I got HG, learned about competitive battling (EVs, IVs, and Natures.) and what was viable and what wasn't so, I felt like I was the dumbest Pokemon Trainer ever. But it doesn't hurt to reminisce.
So, what are your favorite experiences of past games?
