Whilst as you now, I agree overall with you on this, Skyrim does have large populated cities, in fact the characters are also generally much more interactive than those random lines of the Witcher's npcs. The smaller towns are less populated, but still largely more interactive.
Then again I never played vanilla properly, but I remember watching my mrs play the 360 version and didn't notice the towns being any more sparse.
They are quite a bit sparse IMO. Compare them to Novigrad.
I agree people being more interactive and each and every one of them having a job, a routine etc. But to be fair, I don't even know why they bother with it. Sure, you killing some guy might make his wife go to get woods herself and being killed by a bear, and that is hilarious when you read in some gaming website, but at least for me, it didn't make my experience more enjoyable. In contrast, going into the biggest city in the region, and feeling like you are in a village after it has been attacked by aliens and so most of its people were abducted made my experience less enjoyable. Also, the very shit (and repetitive) voiceacting in addition to my character being a mute made the experience less enjoyable.
Anyone else think that Mass Effect 3 would've benefited from having the player get given an ending based on decisions across the trilogy, like what Witcher 3 did regarding Geralt/Ciri's fate?
The whole having to decide the fate of the galaxy right there at the end of the game made all of the previous decisions feel meaningless. At least Witcher 3's one made you feel like there were long lasting consequences based on your choices and interactions over the course of the game.
Definitely yes (or for that matter BioWare's Dragon Age: Origins did a better job than Mass Effect 3 in that aspect). But, my biggest problem with the ending was that it just didn't make sense. The entire first game is about stopping Sovereign calling the Reapers from Citadel, the entire second game is stopping the Baby Reaper being created, because otherwise he would have gone to Citadel and get Reapers back. But then in the end of the third game you see that the guy who controls Reapers actually controls Citadel too, so what was the point of the first two games? Did Mac Walters actually played them or he just had a very bad memory? And of course, the entire 'rationalization' of Starchild about his motives being totally stupid, and he just changing his mind after he sees Shepard and giving the options (instead of you know, just ignoring Shepard and continuing the cycle). And yeah, the omnipotent Reapers being actually just mindless pawns.
Not having any choice is something that I would have been fine with (or at least, I would have been fine with if Casey Hudson didn't scream for two years how much choices will matter in the third game and how the number of endings would be bigger than in any other games). Having a genuinely awful ending, which made no sense in any shape, in addition to making the stories of the first two games pointless was something I wasn't fine off. Artist integrity and all that other shit, but I think that BioWare should have bit the bullet and totally change it (perhaps going back to Karpyshyn's original ending) and then have a look at itself before going for the new game. Instead, everyone decent left the company, and they promoted the biggest idiot on town to game's director.
