I tried to get the real ending on the Steins;Gate visual novel, which requires almost no interaction, and it was near impossible. It turned out that, through nearly 10 hours of content, you have to answer text messages in 6 specific ways in a row at 6 specific times, and the multiple choice usually gives you 3 or 4 options. If you get even one wrong, or you don't answer at the right time, you get stuck with the retarded gf at the end, and you have to start all over and go through this insanely long script.
