These games have what every game should have: fun. With beautiful graphics and animation, a nice soundtrack and lots of humor, your mission is to make your neighbor go crazy using things you can find in his home or in the places he visits on holiday (Neighbors from hell 1 and 2, respectively). It's not always easy to get the maximum score, but you will retry each level until you get it (by maximum score I mean at least 90% in the first game and blowing the whistle in the second one).
The characters don't talk, they just make noises, what gives it a funny and special touch. It's like watching a silent film with its graphic humor but you control the action. The only thing I don't get is the TV show thing in the first game. The game would have been exactly the same without that, except for the background laughter.
I recommend it. It's very short, even adding the two games, but you will have a very good time playing it. One or two levels at night and you will sleep better.
