I remember playing long time ago quite an unknown and obscure game, which nobody knows nowayaday. It was called Gloria. The game itself was so-so, but I was extremely impressed with it, as it felt like your choices really mattered and it felt like actually playing a game and not just reading through preset scripts.
Out of curiousity, I checked now... it had 45 (!!!!!) different endings!
Any other suggestions for visual novels which have really many endings? (By that I don't mean the amount of bad endings, like for instance, at Fate\Stay\Night, but proper story driven endings).
