The word play is a noun or verb. Only adjectives and adverbs have comparatives and superlatives.
The adjective "playful" and the adverb "playfully" use the word "more" or (the) "most" to form comparatives or superlatives.
No, fakest is not a real word. The correct superlatives are more fake and most fake.
