Saenai hiroin no sodatekata

As the fledgling game development team works to assemble itself and the dating sim they are creating, the in-universe characters discuss the many tropes the game is following, trying not to overuse, or outright violating. At the same time the viewer gets to enjoy the characters paralleling those tropes in their own lives. The show occasionally leans on or breaks the fourth wall and lampshades what it's doing as part of its thorough audit of popular anime tropes.

Expect to laugh all the way through Saekano, and to interrupt your own linear watching by replaying scenes multiple times, so as to fully enjoy the layer cake of entertainment.

Note that episode zero serves as an out-of sequence introduction to all the characters' fully developed personalities and relationships - couched, of course, as an in-story discussion of how to best introduce the characters in the game they're working on.

Do yourself a solid and be sure read the lengthy TVtropes page for this anime only after having fully watched it once, unspoiled. Spotting the many subtle references and jokes for yourself is a big part of the fun.

Brilliant work, through and through.
