"Life before death, strength before weakness, journey before destination." - The First Ideal of the Lightweavers (The Stormlight Archive)
The Others feels like a one and done kinda game. They used most/all of their ideas during the KSer and it's doubtful that retail makes them too much money.
My gut tells me that any game that goes heavy with KSer Exclusives will tend to generate more sales during the KSer and less sales at retail. The occasional gamer might walk into a store and see a game like the Others on the shelf and pick it up. Most will probably research it and a little research shows them a ton of content that they will never get (or at least not easily get).
Except for the fact that this game was one with very few KS exclusives (compared to other CMoN games): 2 special enemies and a team of heroes. Everything else: most of the teams, all of the sins, the apocalypse expansion, etc. will be available at retail.
