I am looking for a single word (verb) that means to make someone dislike something or make them not do what they are doing. The following example might better explain what I am looking for.
Example: I was going to play an online game. My friend was sitting with me while I was playing that game. He criticized that game so much and narrated so many disadvantages of the game that he made me dislike or kind of discouraged me from playing it (even though it could be a good game). So I would like to say:
"My friend criticized that game so much that he -----WORDed----- me the game."
Any help would be appreciated.
