Honestly I didn't think so many people in this site where such big fans of dating sims, I mean other than Katawa Shoujo most people have never went out of their way to play them. Well honestly I really liked it in School Days when...oh am I talking about the wrong thing?
Seriously though: I still love the hell out of the School Day endings, even though they aren't my choice.
As for a game - I really loved the endings of Mass Effect 1 and 2, although if I was forced to pick I'd have to go with the first one, since I role-played Mass Effect meaning I had a mix of Paragon and Renegade points, meaning I couldn't get Miranda's loyalty, which kind of soured the ending because I couldn't complete the mission with everyone alive.(To this day Miranda is my least favorite Mass Effect character
