Moving this here so we don't get off-topic. XD
Yeah, Unova definitely disappointed me with its linearity...I mean, half the map is only accessible after the E4. At least the 'post-game only' area of Sinnoh is separated from the mainland by a sea. XD
To it's credit though, Unova does have some annoying-to-navigate caves as well *coughchargestonecavecough*, but it's not nearly as annoying as Mt. Coronet imo. XD
