Way I see it, it isnt a game i would BUY but i would play it considering literally no i know still uses the word dude it makes absolutely no sense why the hell onii-chan was change to it i haven't played this yet but im probably gonna avoid that girls route since..... well I imagine at emotional moments and H-scenes it would just completely ruin the immersion, im surprised MG would even let that pass..... Well there is a lot worse translations out there its just unfortunate such a choice was made also on VNDB there is patch for the names so if you really want to you can try that
