But long story short. Yeah the grinding certainly isn't noticeable when it isn't in the least bit required to progress.
Well if you were unable to beat the game, it certainly was required to progress. The game was pretty easy, but it was just so fun.
As far as the last autosave goes, the game does not save progress made during quests, so you can load up your game, spawn in the guild and develop all of your skills.
You will also find that in Fable, you will always run into the armor and weapons necessary to progress. It's made to be simple and indeed it is, but it was oh so fun. Invest in the Lost Chapters, a lot more content is added to the game and it is not quite as easy.
Why thank you >:)! No-Lifing is my life's work >:).
