If you look at the bottom of each, they show which tiers get which badges.
Digital tiers: Kickstarter badge is included in the $35-$80 tiers.
Physical tiers: Kickstarter badge is included in the $65 and $75 tiers.
There is no overlap with the KS badge and the other badges, though I'm not sure why. I have to wonder if some higher pledges wouldn't have preferred having access to the 'K' badge.
Ah, I see. I was only searching the text.
Anyway, it seems to me that Larian really ought to just give every backer a forum badge. After all, they did end up putting every backer in the KS credits in-game, and they did end up giving every backer alpha access.
But maybe that opinion would hold more weight if I at least had my weresheep badge.
