I choose the options I think might work, but sometimes when I've already gotten bad endings with my choices, I look for a guide for the route I like to achieve a good ending.
If there is no guide or walkthrough available then i just save before the choice and try them all and see which one i liked the reaction to better lol! But i always follow a walkthrough to get the character and ending i want so i guess you could say i mostly play in a strategic way
I feel that I'm more of a strategic player myself. I've learned the hard way that picking options from the heart, will more than likely… just get me a bad ending lol. So I usually just pick my fav LI and save/load till my fingers fall off. Then once I get all of his endings, I'll continue to do the same with all of the other LIs.
Sometimes, if I'm feeling extra festive, I'll go back and check one more time for any secrets I may have missed. I know it's extra, but I love being thorough in my play throughs.
