I think DoA series is more friendly to newbies. That's just what I get from past series.
I know it can be competitive online. Still I always had the impression that DoA has so much fanservice that a lot of people just buy it for that.
Deep down this is probably one of the reasons I'm even considering this purchase.
So as long as the game has a decent community (enough to play), and the game is fun, it should be alright for me.
