Shambhala: 35$ is a little much...
Telika: But compared to what ? To the "normal price" of a single adventure game (as opposed to a pack of five) ? To the "normal price" of indies discounted to dust in bundles ?...
A "normal price", for a single (and often bad) computer game, is usually around $60.
Telltale games are overpriced compared to basically every other game on this site (only exception I can think of is Blackguards), even more so considering they've been out for a few years already. To compare within their genre, the more recent Deponia games are "only" ~20 USD.
Just comparing numbers though, not judging whether or not they're "worth it" -- to me they're not, but that's completely subjective of course. :)
