First i play blind until i reach an ending, then I use a guide to get the good endings and the bad ones. I don't really have a preference for bad or good endings; I think it depends a lot on the game history–sometimes the bad endings aren't that bad at all yk ╮(. ❛ ᴗ ❛.)╭
Usually I only replay my favorite games and routes, but I tend not to replay games I really like too often. I'd still rather spend my time playing new ones.
Lmaoo I'm surprised by the amount of ppl saying how bad Diabolik lovers is!! Thank god I've never listened to the ppl that kept telling me to play it T T
I do 100% with every game I play, even if there are routes or endings I don't really like. I just think it's a waste to not enjoy everything the game has to offer or not appreciate the developers effort and hard work properly.
At least for me, character design is the most important. Not only to attract you, but if the character design is good enough to tell a story, you're more likely to sympathize with and understand that character better.
Then of course comes the plot. If the plot isn't interesting, then it's more...
