The great thing I like about Google+ is they have introduced powerful gaming which you don't see much around on Facebook, I always loved playing Monster World whilst there are so many new games now. Army Attack and A Google a day is something amazing too You can list down the games you love to play.

My Top 5 Games are

1) Monster World
2) Army Attack
3) A Google A Day
4) Zombie Lane
5) 8-Ball Multiplayer Pool
