Okay, I have only played through the game as an evil tyrant, and I have no major problems with it. I do wish, however, the auctions were there so I could sell the weapons I do have for the weapons that could get me the "get all 50 legendary weapons" achievement. But, like I said, other than that no major issues.
I personally like the fact that there are no more start, pause, or any other kind of menus. I mean, it's definitely a little confusing when you first press start and the game doesn't really pause. Now, onto some things that I thought made this game fun, enjoyable, and all around the best Fable yet.
First off, when you buy property, of course you can set rent or profits (whichever the case may be,) but you also have to keep it in good condition. If I were to go and buy an old beaten down piece of crap starter home, I wouldn't want it to stay like that all the time, the same applies here, you have to keep the condition up to keep the rent up. Keeping the rent up makes you more money, making more money lets you buy more property, buying more property only speeds up the money making process, and money is something that you'll need later on.
While, yes, the gameplay is almost exactly the same as Fable II, it still is fun, and the flourishes are AWESOME! One flourish especially impressed me, my hero took his sword, threw it at the enemy, and stuck his foot on his chest and pulled out the sword, sending the foe flying back. Now, having said the awesomeness of the combat, I do still hate how the magic is handled. Every spell can be used essentially the same way, as an area attack, or projected to a specific enemy. While that blemish remains, there are plenty of chances to be impressed, I just want to spoil them for you.
The story is somewhere in between Fable I and Fable II. Maybe this explains it: Fable > Fable III > Fable II. Fable I's story was my favorite, it felt as though it had the strongest pull, and ability to keep your attention. While Fable II story was fairly strong, the last boss was a joke, Lucien just talks, and talks, and talks until you shoot him, and if you don't Reaver will, just a bit disappointing. Fable III keeps your attention while making you guess on the final outcome. Let's just say, you will not expect the final boss. And speaking of Reaver, he's back, and as dispicable as ever.
In conclusion, if you liked the last Fables you have to try out Fable III. It may not be the best, but in my opinion it is. It has everything a Fable fan could wish for, the Fable style, Fable II gameplay, and the over all Fable style.
