Honestly, I dont play the 3rd gen games anymore. Mainly for two reasons;
Firstly, I really enjoy playing D/P and love anything about the 4th gen. So I really dont have time and dont fancy playing R/S/E. Secondly, my 3rd gen games are all European ones so I cant use Pal Park to transfer 3rd gen Pokemon to my american Diamond game.
I only "use" them to catch the GBA Insertion Pokemon.
