The press release says, "The agreement broadens Telltale's product offerings into new genres and new styles of gameplay."
We clearly can't expect these just-announced titles to be the usual Telltale point-and-click fare. As much as I love their adventures games, I think branching out into new genres is great for Telltale. But I'd need to know more before I could say whether or not I'm interested.
On one hand, if I'm going to "be" in the Jurassic Park universe, I'd much rather have an action (or action-adventure) game than a straight-up adventure. But it ain't easy making successful, compelling action games. You can't just graft action elements onto an adventure game style -- you end up displeasing fans of both genres.
Or maybe it's something else entirely. Anyway, I'm looking forward to learning more details as they emerge.
