Is there a chance of success? If not, then it's a cutscene and loses a great amount of its drama and impact for me because, again, it's predetermined.
The greatest sense of loss I feel in a game is when I lose something I could have saved. The greatest sense of victory is when I save or gain something I could have lost. Especially when that loss, or gain, is permanent. The more dire the odds, the sweeter the satisfaction. I also don't like being told that 'I should like this character' or that 'this character is obvious comic relief, laugh at their antics', which is what a lot of games(especially anime-style ones) do. In FFT, I actually dismissed TG Cid. Yeah, the most overpowered unit in the game. I kicked him out in favor of my generic units because I'd forged personalities and relationships with them and I know I risk them every time we step on the battlefield(lol what a nerd). Who's this yahoo and what right does he have to take their place? Power? Who cares?
Despite its simplicity, there's a mod called Brutal Doom in which you can save fellow Marines from demonic slaughter. CAN, being the key word, since if you're spotted and you take too long they'll be butchered and the body will lay there as a reminder of your failure. If you're fast enough upon being spotted however(and accurate enough with your weapons, I found out friendly fire isn't when I unloaded a rocket launcher into a dark monster-filled cage to hear a very human scream among the death cries), you can save them. That's accomplishment and satisfaction, at least for me. If the spoiled character's relationship can't be salvaged, then its loss has no real impact on me. I'm sure folk thought Aerith's death scene in FFVII was one of the most infuriating and saddening things that could have happened to the player. I barely registered it because I never used Aerith and quite frankly just didn't engage with her(I was a Barret/Red XIII kinda dude).
I'm not saying you can't like Shulk, I'm saying this is why I don't.
