I am a seiyuu fan so I will check the VAs before buying the game. I personally love Furukawa Makoto and Kimura Ryohei. I will prioritize playing otome games voiced by them.
I am currently playing Cupid Parasite. It is my first otome game and I love the graphics and VA. I plan to play its FD (Cupid Parasite: Sweet and Spicy Darling) once I finish it.
I first look up the recommended order for the routes to get the best gaming experience, then play blind on the first time and see what ending it takes me to. After that, I search for walkthrough as I have no confidence in collecting all the remaining endings.
