While both have different plots, the MC's personality are exactly the same. Saekano is about a student who wants to create a dating sim while Kami nomi zo Shiru Sekai prefers a student who wants to get rid of spirits possessing students by making them fall in love and kiss them at the end to get rid of the spirit. (same way Date A Live works) The MC for both is a student who lives for dating sims day by day and has a long history of dating sims, to the point where both anime revolve around their obsession with it.
