Lol, i's amazing just how much people blow things out of proportion. Look, I don't particularly like Xenogears, and I think I've made myself clear on that. However, saying that 75% of the game is cutscenes is just flat out wrong. It may FEEL like that (and that's not a good thing), but the reality is, there is no RPG out there where more than half the time is spent in cutscenes. Battles take time, dungeon exploration takes time. These things may not be as temporally discernible, hence the tendency to under/over estimate the time spent on these gameplay mechanics. Basically, the moment you introduce battles at all, you're pretty much guaranteed to have them take up a minimum of 50% of the game. They're repetitive, so we often loose track of just how much time we've spent doing them. But looking back on it, Xenogears has a fairly large number of major dungeons, many of which are not just a quick walk in the park. Some of the Gear boss battles, alone, I remember taking up to 30 minutes apiece.
Now, why would anyone say that 75% of the game is cutscenes? Because it does feel that way some times. Much of the writing is dry and descriptive, so if you're not fascinated with the story, you're going to have to slog through page after page of descriptions of things you don't give a shit about. The character dialog is NOT WELL WRITTEN either, being, once again, very utilitarian and often forced (this may be translation issues, but I sorta doubt it). So, again, wading through text you don't give a shit about. On top of that, there are two dungeons that were replaced by text cutscenes on disc 2. When you break it down, this entire period is probably about 45 minutes TOPS. But because it's so horribly conceived it sure feels like hours.
Well if it feels like it takes hours then that obviously means the gameplay took a backseat, which shouldn't ever happen in a role-playing game. Yeah, no RPG is gonna have 75% cutscenes, I was exaggerating that for emphasis. But either way anyone spins it, Xenogears has cutscenes that are way too long. It's like they didn't even want you to play the game so much as have you read the script.
