The Gen 6 Pokemon games are often criticized for lacking a third, definite version, but this generation brought the series into a whole new dimension, being the first mainline games to be released on the Nintendo 3DS. Pokemon X and Y were also notable for introducing the fan-favorite Mega Evolution mechanic that added a new layer of depth to battles and allowed certain critters to evolve beyond their normal potential. Gen 6 is considered by fans to be one of the easier sets of games in the series, but there are still some challenging aspects that players will want to ensure their team can tackle.
