Gen 3 games. That was when I lived beside my 3 best friends and we played Pokemon all the time. --- I wish Blastoise was my dad. He wouldn't beat my mom like what her boyfriend, Johnny does. If Blastoise was my dad things would be different around here.
Gen II for me. I played the snot out of Silver and Crystal for many years after they first came out (Silver was my first pokemon game).
As a result, I've played HG/SS almost as much. I love the improvements (especially the lead pokemon following you and being interactive). --- My Disgaea fanart: http://succubii.deviantart.com/gallery/32013434
4th gen. Looking back, I prefer 3rd gen but didn't play it as much. --- With each passing day, the world finds new and exciting ways to kill a man.-Balthier FFXII Official Leanan Sidhe of SMTIV & Vaporeon of Pokemon XY boards
