I was fine with it a while back when it was announced, but now that all this cool info is out, and I've been fantizizing about all the stuff I'm gonna do. Then I rember the fact that as soon as I finish the main quest.... It's over, and I gotta restart. :sadvaultboy:
You could also wait until after you've done all the things you want to do before finishing the main quest.
And that's why it doesn't bother me too much that the game has a definate ending, now, I will say that I would prefer if it did not, because Fallout is the kind of game where there may be a lot of things you can do other than the main quest, and I would like to have a chance to actually DO those things before the game ends, but at the same time, it sometimes feels a little strange for you to suddenly start completely ignoring the main storyline to do other things just before the final confrontation, which is often where a story is at its most climatic and creates the strongest sense of urgency. Still, Obsidian has said, I believe, that they considered making the game open ended, but decided that their ending would be cheapened by allowing you to continue playing after it, and when they saw from Fallout 3 that there is some demand among the fanbase to be able to continue playing after the ending, I'd think that if they still think a definite ending would be best, then they probably mean it.
you die a hero (or not) and the world goes on without you.
Dying a hero only works when the sacrifice actually MAKES SENSE, in other words, when it's the last desperate measure, this wasn't the case in Fallout 3, there were three companions available in the game who should have been able to enter without fearing radiation, and there is no reason one of them could not go in and do it for you, at least there should have been no reason why he could not have, except that the plot says so, which is the biggest problem with Fallout 3's ending. You can't just ignore logic when writing a story and still expect it to be well recieved.
In this case, though, I'll trust Obsidian to do better, since I've never considered story to be the strongpoint of Bethesda's games anyway, plus, after seeing the reaction to the messup with Fallout 3's ending, I'd like to think that Obsidian knows that they need to be more careful about ending the game in a way that makes sense.
