pokemon legends arceus is the most fun i ever had playing a pokemon game. i loved the free roaming in the world, sneaking up behind pokemon and trying to catch that freaking snorlax over and over why won't you stay in the heavy ball!!! oops, sorry where was i? i could spend hours playing the game and accomplishing nothing and not feeling bored. it reminded me a lot of how i played zelda: breath of the wild, i would spend hours exploring and fighting and not accomplishing anything but still having a great time solely because of the gameplay.
pokemon x and y were also incredibly fun, i enjoyed the 3d world but but main reason is because of the world wide release. i have NEVER had good luck against japanese players in the past, they would usually have much more time learning new gameplay elements and moves than me, but for the first time i was on equal footing and i was defeating people all over the world. hehe, i played online much more than i ever did in gen 4 and 5 i also had many local battles in college so gen 6 was a great experience for me.
pokemon coliseum was very fun too, i was glad that the cities had to be fast travelled too since i am not a huge fan of wastelands, but the cities and towns looked great and i enjoyed the pacing. having every battle be a double battle was great to me, i felt they were underutilized at the time in the main games so it was very fun for me. i just wish they had 386 rental pokemon available in multiplayer mode like in the pokemon stadium games. if they every made a port i hope they would put forth the effort to do that. my goal has been to make all 251 original pokemon level 55 for pokemon stadium 1 and 2 (a living dex so that includes metapod and kakuna at level 55) but unfortunately whenerever i get close, the pokemon stadium connector (the thing i put the gameboy game in) corrupts the data somehow and i have to start over... has anyone ever made a full living dex with good moves for pokemon stadium 1 and 2?
