Queen has an odd habit with their keys. They are either extremely active and fun (Bohemian Rhapsody, Somebody to Love), or flat out boring and sparse (A disturbingly large amount). Thankfully, Play the Game belongs to the former.
You get plenty of movement all throughout the song as it sends chords, single notes in a slow, but fun manner. During a few wacky parts, it may throw a bunch of chords at you at once, which are fun to (try to) nail.
Plus, unlike many other keys songs, you are playing for the WHOLE SONG. That's right, no stops, no 3-minute breaks, heck, the guitar has more breaks than the keys!
This is not a hard song by any means, but it's fun, engaging, and it's Queen. Plus, the other instruments (besides guitar) are not bad at all either.
Unfortunately, the Extravaganza 01 pack's only good keys songs to go along with this one is We Are the Champions. If you've got other instruments, go ahead and buy the pack.
... Dammit Queen, you manage to troll the entire world years before The Game was even created. You clever masterminds you...
