Probably the media. I swear, they put these games out in front of the same asshats who just play Halo and CoD all the time and expect them to be able to understand the game? TES isn't made for these people, it's okay if it's too "spreadsheety" for them.
I think this is a serious issue for TES, and its why I accept I am no longer their target audience.
Sure some people who like shooters like RPG's. I love Halo, and Halo 1 ties as my favorite game with Morrowind. But certianly not everyone is suited for RPG's.
Bethesda wants the mass market to play their game, for financial purposes. So the end result is simplifying it. RPG's are a dying genre.
Honestly I think thats why we now have dragons. Because the mass market, that is interested in fantasy games, says, "I can kill dragons, sweet!"
But of course we need to draw the line on complexity somewhere. Is Fable too simple (yes), is Dwarf Fortress too complicated (really depends on the person, although it has other issues)?
People of course have their own opinion on simplicity. I personally despise it. I feel it reduces roleplaying, and I think it removes the effective modeling of a character TES games have had. Fable does a terrible job of modeling a character, and I feel TES is headed in that direction.
I do however like some of the changes. I like the idea of perks, I'd like to see them occur automatically at certian points of a skill, much like in Oblivion, but I'd like the number to be similar to what we are getting now. Not 4-5 perks per skill like Oblivion. I like how one spell can do different things based on context. I even like parts of the dual wielding system. But we are losing more than we are getting in my opinon, and we are losing it not because they are incompatible with the new systems, but because Beth has chosen simplicity and instant gratification over complexity and depth. And that I have a problem with.
