Gamer question Playability and gameplay (how to use in a sentence)

Hi

Here is the wiki

http://en.wikipedia.org/wiki/Gameplay

1 How do you use Gameplay an playability in a sentence?

I'm trying to say something like this

• The gameplay on this game is a lot easier than on battlefield 3.

• The playability of this game is a lot easier than on battlefield 3.

In wiki, playability means I quote "the ease by which the game can be played."

2 Wouldn't it be "the ease with which the game is played" the grammatically correct way to say it?

Which is correct?

• This game is played by great ease.

• This game is played with great ease.
