i feel Pokemon games are getting more complicated in very minor aspects. The transition from Red to Silver for me took a long time because at that time i never researched anything and just played the game as it were handed to me. The transition from Gen 2 to 4 in my honest opinion wasn't that hard but i struggled getting used to all the changes in gen 5.
Did these changes make things a little harder? Maybe just a little. But they also made things easier at the same time as long as you payed attention to the new set of rules.
