But even Illusion, which is the biggest studio for this in japan does disappoint in terms of making good content. Most of their games are 90% dull chat, 5% character movement and 5% sex.
Japanese makers put a lot of focus on the story actually bc thats what fans here enjoy. They have dedicated and experienced writers. It's not uncommon for the story to be a huge part of the budget and once you get into it, its not all that dull… At least not the good stuff!
