[2021] How certain is it that there will be no new Tems ever after this last island is released?

Hi! It was said that it's unlikely for new tems to be released, but that does absolutely not equal or mean that there won't be new content added. There's a lot of stuff that's content apart from tems, and there are tons of plans for the post-launch era.
We're also choosing to be as honest as possible now, early on, and not to give expectations or false hope if we might not be able to fulfill. Post-launch is still far into the future, too, so nothing's set in stone yet and there's a lot we cannot talk about.
Temtem as it is now already provides a huge chunk of playtime and entertainment, and there are great things coming even before full launch, but ultimately it's only up to you to decide if the game seems interesting and appealing enough for you!

That’s totally respectable :)

I personally don’t think it’s a great idea to approach a game for where it stands against others, instead of for what it is. We are Temtem, not “the Pokémon killer” some people paint us to be. We’re also not a multibillion, 25-year old company; we’re a 25-people team. And all our regions and tems are in one game haha That said, nothing wrong in not wanting to get a game! Games are about fun.

My point is what I said. We’re not Pokémon nor a clone of it, we’re Temtem and as such are different. Expecting from Temtem what you missed in other games will probably end up being disappointing because every game is it’s own things, goods and bads.

just seeing this now, sorry! It's indeed early, but I believe there'll be something for everybody :) don't take this as a promise just yet, as you said it's early, and we'll be able to be more specific when the time gets closer! (alsohappycakedaylol)
