"The interesting thing is interaction ...Maybe I just like what I am doing."

You're not interacting. That's the problem. It's as if you're a guest at a party and you're talking and talking and talking and not letting anyone else speak a single word. You're not allowing anyone to interrupt your monologue.

No one else can play until you are finished when you reserve four squares on a level. Please tell me whether or not you understand this. On the other hand, if you reserve only one square, others can participate.

A gridhog is like a slow donkey cart on a single lane country road. Several automobiles are behind the donkey cart... The autos are forced to drive very slowly. The drivers of the autos become very angry. A gridhog is like a roadhog, in other words.
