@Mandea You should care about reviewers, because they indirectly decide of game acceptance on market. Bad acceptance = bad sales = bad studio income = no next game in series
If KB is only funded by sales of game to fans, it would burn to ground long ago, games today need lots of advertisement, and marketing and neither of that is easy to get with game that got bad reviews from major gaming sites.
Kb- the Legend got great marks, it was new and interesting and lots to fun to play. KB-AP still got good marks but for same graphic and engine, it didnt gave impression like lots of new ideas were involved in making that game (only adding more content to old recipe), same thing goes for CW. I think more change to game was Red Sands mod with new island and changed flow of game, then CW with orc race adrenalin.
If this KB-WotN gave us same looks and mechanic engine like previous games we as old fans will still buy and play it. But new players wont like it much if game get crucified by gaming magazines/sites.
