((TL;DR at the bottom)
This has been burdening my heart for some time and I really need to get it out. Once in a while, I come back to Skyrim to tinker around with mods and have some smashing fun. Note that I say 'modded' Skyrim. I've never intended to go back to vanilla.
Before I go on a humble rant, however, I should note that I am a fairly casual gamer that isn't very knowledgeable in how the gaming industry works so excuse anything that I spout out of ignorance. I own no consoles at this time, I do all of my gaming on a PC these days but I did use to own PS1 which I believe still has the most memorable games to date. Which is sad.
Anyway... whose 'brilliant' idea was it to voice every single character in a TES game since Oblivion? It has to be the worst thing that happened to this franchise, ever. Voice acting works in action and adventure and other 'theme park' games where you have a set path and where your choices barely matter as you are guided through the game by the game developers. It also worked in Dragon Age: Origins but that game was also much much more linear than any TES game. In fact, even in DA it bothered me to a great degree. But in a TES game where you have over 300 NPCs or even more, how are you ever going to voice them all reasonably without using up too many resources?
Firstly, anybody who has ever dwelt in the TES CS for Morrowind knows the overwhelming and nearly limitless potential that Morrowind's conversation/dialogue system had. You could play around with countless variables, such as your affiliation with guilds and houses, your race, your six, your stats, your standing with that person, your journal entries, time of the day... science knows what you could do with that thing if you only had the will. Of course most of this potential was largely untapped by the developers themselves. As pointed out countless times, it felt like the NPCs were all tourist guides of some sort, not to mention all said the same thing. Still, there were quite a few unique NPCs with unique dialogue as well.
What I first expected of Oblivion was that they'd actually expand upon this vast potential Morrowind had when it came to dialogue. Instead they decided to go with full voice acting.. and that was just a grave mistake. What was the point of voice acting in the first place? To increase immersion? Ironically, it did quite the opposite, at least for me. Especially in Oblivion where the voice acting was simply atrocious(especially the elves) and they had so few voice actors too. Again, in a world filled with hundreds of NPCs among whom all should be capable of saying something, voice acting is just a bad idea... it seems to have become a new fad... a new standard among all major game franchises. Everything must be voiced. No! Please stop.
But wait! There's so much more to a game than just dialogue, right? Expansive dialogues are just for the hardcoe fans, man. Ain't nobody got time for that. We want to get right into action. That seems to be the main mentality of most consumers judging by the direction most game developers are taking these days. Okay, that's fine. I too think that combat is a huge part of the game and if I do not enjoy combat then I usually quit the game, even if it happens to have other good aspects, like story, graphics etc.
The problem is that voice acting soaks up lots of resources that could have been used to improve other aspects of the game. In case of Skyrim, for example, those resources could have been poured into making magic in combat more balanced and more fun becasue it honestly svcks. But if you think that is just my opinion then how about the atrocious companion AI? Games that were made nearly a decade ago have better AI than Skyrim... not to mention how limited your interaction with those characters(like Lydia) are if you compare it to... let's say, Baldur's Gate 2 or heck, even Dragon Age. Considering that new games are actually expected to push the limits even further this feels like an insult. Certainly, TES games have always been the 'jack of all trades, master of none' type of games but really... this was too much.
Or instead of hiring 10 voice actors, you could have had one creative coder write 20x as much dialogue for everybody in the game. Because voice acting takes money, time and space.
TES series since Morrowind(if I'm correct?) have been released on consoles as well. This means they have to take into account how much data they can fit on the DVD CD. Voice acting takes too much space. All that space could have been potentially used for more in-game areas, more quests, more... anything. A more polished game in general... as somebody who plays only on the PC I'd like it if they just cut the crap and stopped releasing the games for consoles but that's just a pipe dream.
In the end, if I was to sum up what is wrong, with Skyrim and Oblivion, aside from voice acting which I believe contributes to the problem, in one sentence is that they both feel unpolished. Morrowind had that feel too once I played the game for a while and I understand that in such huge sandbox type of games this is probably inevitable but it was nowhere near as close as glaring as with the two successors. And Morrowind had an immense amount of content.
Another point that I wanted to make which I almost forgot, related to modding.
What highly annoys me about voice acting in Skyrim is that it pretty much 'forces' modders who want to make good quality mods involving dialogue to voice act as well. This really grinds my gears. While I've downloaded countless mods that valiantly tried to match the original content, they have always fallen short. People just don't have access to professional studios nor are they professional actors. Neither are most of us even native English speakers! This issue has discouraged me from trying to mod myself and I think I'm not the only one.
Lastly, I'd really appreciate if, for once, I got my hands on a TES game that could keep my attention without me having to run off to TES Nexus after beating the game in 10 hours. Morrowind got me hooked on the series and I'd really like to experience something similar once again without the modders community having to cover up for all the mistakes and misses of the game. And console gamers are screwed over entirely. I feel sorry for them.
TL;DR - Voice acting soaks up too much time, space and money and I really wish they'd stop doing this and revert back to the classic model used by RPGs like Baldur's Gate and Neverwinter Nights where the most important characters and lines are voiced while the rest is just text so they can use all those resources on improving other aspects of the game that have been severely lacking as of late.
