I have trouble trading or talking about Pokemon without Bulbapedia. I don't even know most of their names yet xD
Probably because I haven't paid attention to the news before the game release, unlike before Diamond/Pearl was released. Back then, I was familiar with most of the Japanese names before English version was released.
I don't think I even knew the starter or mascot names back when DP were out, but I absorbed that information (and more) rather easily. It's just all those retardedly designed Pokemon in Unova I can't get the hang of.
(For example, I still forget my Fly HM slave's name repeatedly, and I even used it in the Battle Subway.)
