The visual novel and dating sim market for women is somewhat unique in comparison to its "for men" counterparts. Similar to the allure of BioWare games like Dragon Age versus Square Enix's Final Fantasy, the draw is first on being able to explore a rich and compelling storyline -- and also to be able to control which way that storyline leads.
The majority of these types of games don't actually require you to be 'good' at playing other games -- save for a few mini-games here and there, you generally only need to have a decent command of the English language and the ability to make up your mind.
Most otome game plots start out rather formulaic, cheesy, and generic, especially since it requires you to be introduced to a number of eligible 'catchables' as soon as possible. It's only when you decide to stick with it and keep exploring new characters, new interactions, and new storylines that the beauty of storytelling really begins to shine.
