Fable 3 was even worse than 2 and 1... by a lot. definitely rushed
But thats not what Bethesda is all about. They spend 5 or so years on each Elder Scrolls. They give it all of their love, like it were their only child, and they end up with nothing less than a game far superior to any RPG we have experienced.
EDIT: Some game franchises have the ability to just change a couple things, rush it to the market with a cool new title and they will be consistent best sellers (Call of Duty/Halo). Some games try to follow thier lead and they fail miserably (Fable/DA2). And some game developers know what their game is all about, and they wouldn't make such a stupid mistake (Bethesda)
Halo rushed? I think not. Halo Combat Evolved: November 15, 2001, Halo 2: November 9, 2004, Halo 3: September 25, 2007, Halo Reach September 14, 2010.
I wouldn't call a three year development cycle a rush. Especially when you take into account Halo being a shooter. Whereas Elder Scrolls is a huge open world RPG. Three years is certainly enough time for a Halo game.
*ODST Released in 09 but that was more of a smaller spin-off so I don't count it. And Halo Wars was made by a different studio.
I agree on the Fable point though.
