For the clincher, i would put your opinion on whether or not you agree video games are positive, and then give a statement as to why you think that.
1. Personification. Chimneys do not have legs, nor do they bounce on fours. The act of personifying is to give a non living item human qualities.
2. Metaphor. The sentence is comparing a bridge to an eye without the use of like or as.

4. Likely a simile. This sentence is comparing the bride to a fan while using like.
Commas are used when two independent clauses are joined with coordinating conjunctions (For, And, Nor, But, Or, Yet, So).

However, there are always exceptions to this.
Hope this helps:)
