Just a question, you all seem to hate it for one reason or another but I bet you all still put over 200 hours each into it? If you all hated it that much why did you play it? Fair enough it had its flaws but why rag on it so much?
Not that many players actually
hate it. If sold extremely well, received very high ratings and good reviews almost universally, and is
still being played a fair bit - yes, even now!
That said, there are some people who will hate just about anything (or anyone), given an internet connection and the belief that everything they do or say online is "anonymous". Oblivion is hardly the first, nor the last, to "suffer" from this predictable, childish behaviour.
And, aside from all that, there are also some legitimate criticisms that can be made, no matter how impressve the game is/was. Many of these, some will interpret (disingenuously or otherwise, and indeed, right or wrong) as "hatred". So it goes...
Some of what is "wrong" (though, yes, if could be said to be subjective in some cases) with Oblivion can be seen by overviewing - or in fact,
playing - such games as Fallout 3, Fallout: New Vegas and Skyrim. The folks at Bethesda did not necessarily get everything right, with Oblivion, and perhaps they have learned a number of things since then.
The most damning criticism of Oblivion though, I think, would have to be that it lacks "soul", and/or "depth". When compared to Morrowind, as it is often claimed. In certain ways, the bar was set very high with TES3, and unfortunately - according to some players - Beth missed the mark (
in that way) with TES4.
You could look at some of the more popular mods of all time (er... except the obvious kind!) and get some idea of other issues gamers have had with Oblivion. As it so happens, if you play using a PC, issues will sooner or later be sorted out.
