Telefang did latch on the popularity of
Pokémon twice: once by being a differen take on
Pokémon, once by being pirated under the guise of being a sequel of Pokémon. People were initially fooled,
TRSRockin se them straight, others eventually either laughed at how messed up the text was or unironically enjoyed the games on their own terms. To nnes of Pokéfans,
Telefang was their first Pokéclone, which would have had them interested in other such games.
I say there is more to
Digimon than
Cyber Sleuth: the people during the old
Pokémon vs
Digimon Fandom Rivalry (especially back when
Digimon was thought o be a knockoff of
Pokémon) grew up in multiple ways, most eventually embracing both and eventually branching ou t other similar games.
