Started Panzer Knights last night and finished it 15 minutes ago, so not not technically playing... but it does have some content left in it still which I just might have a go at later.
It's anime, it's girls, it's panzer, it's got some War Thunder (or World of Tanks, I forgot which) inspired gameplay but not too in-depth. Best thing I can say about it is that it's got what's needed of a game and it really makes you feel the frustration of being a German panzer commander in the eastern front, despite the lack of an atmosphere (like from say, Red Orchestra).
