I'm speaking for myself, but I think a lot of gamers can relate to this.
Gamers usually appreciate having some similarities between games, as it gives them a sense of familiarity and helps them know what to expect.
I've recently heard we're using the name 'Repository' or 'Illuviary' for our Illuvials 'Pokédex.' I think this is terrible branding. The name, for obvious reasons, should be 'Illuvidex'.
As for our Illuvials marketplace, currently named 'Illuvidex,' we should just call it what it is: 'Marketplace'. It's not even decentralized, so using the 'dex' suffix is a bit misleading.
