indeed.
if fonv is possible, why is skyrim so damned shallow? I don't think there were quite so many factions in FONV as MW even, but even so Obsidian managed to make PC decisions matter.
Priorities, really.
For one thing, Obsidian
actually has writers. A whole team of them. To my knowledge, Skyrim's lead writer is a journalist/programmer, as in his writing experience is more factual rather than creative and ideally he's actually more of a designer than a writer. Another thing is they fully believe in the old school RPG genre. Josh Sawyer, the project director for New Vegas, recently said on his personal formspring that he got interested in firearms BECAUSE of New Vegas. He researched them so he could use the research to assign each gun realistic-yet-balanced damage in the game. Obsidian actively limits the characters and has you choose what they can and can't do and ATTEMPTS to balance them all.
Bethesda definitely focuses a lot more on world design, not so much on story or NPC interaction. Furthermore, Bethesda believes the player should have unlimited freedom. This goes against the old school RPG genre completely, because they set up speech or lockpicking to be based on a chance of a minigame. Lockpicking in New Vegas REQUIRES a skill level, THEN the minigame. Lockpicking in Skyrim, anyone can do. Speech checks in New Vegas REQUIRES a certain level of speech, whereas in Skyrim it's fully chance-based. The result is that technically, ANYONE can do anything in Skyrim, the limitations being fully imaginary.
The devs then spend 5 years making rocks extra shiny whereas Obsidian is more interested in simple balance, storylines and quests that tie it all together.
