The Pokemon series naturally lends itself to replayability, with various challenges being developed by the community over the years to encourage new playthroughs. Out of all the games in the series, Pokemon X and Y are the most worthy of a replay in 2025 due to their connection to the upcoming Pokemon Legends: Z-A. Pokemon X and Y may feel somewhat outdated by modern standards, but with the Kalos Region set for a grand return in 2025, now is the best time to dust off the 3DS and start up a new playthrough of the Gen 6 games.
