Yeah, I still play. Well, Emerald at least! If you notice my current location, I'm stuck in Generation III (have been for a long time now) because I don't have a DS Lite yet. And now, Generation V is dawning upon us! :D I'm glad that new games are coming out, but I'd least like to own a Lucario or Giratina before Gen IV ends! :) Working on obtaining Platinum and HeartGold in the near future, and beginning migration via Pal Park sometime later (which will probably be a long time as I have to adequately explore both games first).
But Emerald has some awesome stuff. Vicious starters (Blaziken FTW, my trusty starter and first one ever!), Gym Leader rematches, May, integration of both Team Magma and Team Aqua into the plot, cool cutscenes, Rayquaza, Trainer Hill, the Battle Frontier... I've lost 2 Sapphire carts before, so changing over to Emerald was a bit of a consolation... In my case, the Battle Frontier is at times engaging and other times boring. When you keep on losing right before hitting the 50-win streak, it puts a large damper on the game... Maybe it's my Pokemon...
But yeah, Generation III is the Gen that reeled me back into the Pokemon universe (perhaps permanently! :D) Moreover, it's the gen I'm more knowledgeable about (enough so I can traverse Granite Cave without the Flash HM on one of my party Pokemon).
Funny thing is, it was the Secret Base feature that caught my eye when I first glimpsed someone playing Sapphire.. :) In any case, Hoenn is awesome!
