Ffxi you have to have a pc. And as far as im aware it is beatable since all expansions are out. It might take you quite a while though.

and XIV again is beatable but. Since its not got all expansions out yiu wont fully beat it until its out. Luckily bo endgame raid or whatever locks the main story out so thats good



but honestly. Dont include them in your mission. Play them for what they are not for completions sake. I never counted them in my mission simply because of what they are. Long long mmos with lots of time required to play. And honestly you might just get addicted and forget about the other games xD
