I personally love the variety of the endings. But I REALLY love how they kind of interact, too! Going through multiple routes, I noticed how characters remain consistent no matter which route you go. So stuff you may find out explicitly in one route still gets mentioned (or at least hinted at) in other routes. The main one I always remember is Felix. (Not putting any spoilers here!)
Anyways, I fully support having different life choices lead to different results. =) Keeps things interesting! I actually kinda get bored with VN's that have multiple routes, but all the endings end up pretty much the same (unless you get a "bad" ending). With those, the only real difference in how the story ends is which character(s) your MC ends up with.
