From someone who has played the game since the open beta; I can say that this is a great game.
The maps are all unique in a few ways, some even having traps. (I.e The Gauntlet, Sanctuary Bridge, Viking Village, and more)
The heroes are a bit controversial, every character typically has 1 mechanic that's somewhat unique; but some characters do have overlapping/similar mechanics.
Overall, for honor is definitely a solid game, if you wanna play a game that isn't an overnight master type of game. Take it from me, I'm still learning new things even though I've been with the game for three years.
