>>45919090Gen 4 easily. Remakes of the best and most content-packed games in the series, with even more content added, Platinum being good and also content-packed, both the first age and golden age of online before retarded shit like megas, Z moves or dynamax could come into play, etc.
Gen 2, gen 3 and gen 5 all had virtues too, but nothing tops the sheer content and quality of what gen 4 had to offer. Also PBR, the best 3D pokemon game for battling to this day, was during gen 4.
