Skimming all four I didn't particularly like any of them so I decided to read them all in their entirety and find the two I disliked the most and vote for the other two. The Thousand Dick one read like a long joke not an actual story and didn't seem like it deserved my vote on principle. I do admit it elicited some chuckles for audacity though. The Game sounded more like the prologue to a video game than a full-fledged story and that didn't sit well with me as there wasn't much of an attempt to flesh things out. So by default Friendship and Firefly got my votes.
