Why do people look for gens? Each game has all the previous Pokemon.
usually its because we want to showcase more of the series than just shoving 20 different pokemon from the 1st games then casually tossing the newest games a bone to remind people theres new stuff to buy.. kinda reminds me of my thing with Fire Emblem Reps to be honest.. just a valid and natural want to actually show a series you love for what it truely is instead of giving a false image with poor representation. ( seriously imagine if Mario's reps were Mario, Paper Mario, Dr. Mario, Mario & Luigi and baby mario.. not a very good showing of what the series is now is it?)
