>>33257959>Dragon Quest MonstersLiterally the only series that could stand against Pokemon at any given time in Japan, but it releases too infrequently to be an actual competitor and lacks the worldwide appeal that Pokemon has thanks to NEVER EVER Syndrome.
>WoFFOne-off game (so far) that didn't do so hot for anyone other than FF Fans.
>DigimonNo chance in hell of being a competitor given the lack of interest from Japan.
>Yokai WatchIt had a good run in Japan by capitalizing on children losing interest, but it's fucking dead now.
>MonHun StoriesIt did fairly well in Japan, but I don't think they'll be too focused on Stories Sequels given the sales compared to mainline MonHun.
All and all, Pokemon's too gargantuan for anyone other than DQM to slay in Japan, but that still doesn't consider the fact that no other Monster Catching Games can compare to Pokemon outside of Japan, it has too much of an iron grip on everything to let go so easily.
