It's similar to Mass Effect 2 -> 3 for me in terms of the story. You don't have to play 2, but it sets this game up very nicely plus you'll be able to enjoy and appreciate some of the returning characters.
Eh... no that much.
I think it's nice to have the context of previous games in The Witcher 3, but in Mass Effect 3 the whole point of the game was to finish the story of Mass Effect 1/2. ME3 can be fun at its own but I wouldn't recommend it to a new player.
