Highly recommended for a newbie: Warzone Heroes
I think it's pretty good!
First of all, it's a card game, World War II style, borrowing parts of "Royal War" in gameplay and adding quite a few innovations of its own; the generals system allows for more varied tactics and faster paced gameplay that's also more exciting.
Then the point comes! This game is surprisingly global! In this game, you can meet the United States, Japan, Britain, France and other countries players, you know, to win a hand is really all over the body! It's like beating up other countries on the battlefield, it's so cool!
Seriously, I can't say enough about it, but I think it's something you'd like to see for yourself, so go ahead and experience it!
