Just wanted to correct that the new anchor mechanic should logically be listed in the inspirations and credits Assassin’s Creed Black flag, because that mechanic is from there. But as I understand it, they did not do this, because listing all the mechanics would simply clog the sheet?
Not every feature is “inspired” by something. Sure it might not be original but people can think of ideas themselves. Don’t “uhm ackstually” stuff like this
Like Viv said, the feature probably wasn’t directly inspired by AC Black Flag or any game and may have just been something Vetex thought of himself. Or as you said, he may have just not wanted to put every single mechanic onto the sheet and only stick to the most important ones.
Not in every game, an anchor can save you from an accidental enemy attack, read again what the meaning of “anchor” in this mechanic is.
There may be several other games with similar mechanics, but I included Assassin’s creed 4 black flag because it’s on the list and because it’s quite an old game.
