A few changes I would have liked to see changed, and caused a major disappointment for me:
NPC INTERACTIONS
Gifts - I cannot give gifts to villagers anymore like before. I should be able to gift like in Fable 2 if I chose to.
Expressions - I think its an interesting change to include a generic "good" and "bad" expressions, but that was the same in Fable 2. The only difference was in Fable 2 we were able to either use the generic expressions via the D-Pad, or you could choose one of your own from the expression wheel. I would have expected the same from Fable 3. Some have expressed their distaste in certain expressions, or how it didn't fit for their character, but they have only a single good or evil choice. I would like to see an expression wheel brought back in a patch.
AoE Expressions - In Fable 2, using an expression in front of a crowd caused everyone to benefit (or not) from your expressions. Playing a lute in front of a crowd well caused everyone listening to gain happiness from it. Performing a rude gesture to a crowd caused the entire crowd to be displeased. Fable 3 only allows 1 NPC to change opinion now, when it should continue to attract crowds. If I stand in the town square wearing nothing, and giving everyone the middle finger, the entire city that can see me should react accordingly, not simply the single person I have targeted.
DOG
Behavior - Several times PM said that the dog would not be as obedient as in Fable 2, and mentioned that it might chase rabbits/etc. I did not personally see this, even when testing it. Was this included?
Behavior (optional) - My personal idea when PM mentioned a non obedient dog was that I might have to spend a little time training my dog. It might not find dig spots every time, and I would need to pet or punish the dog to encourage or discourage behavior that I wanted/didn't. This is an optional change I was expecting and was let down that it was not what the designers had in mind.
SANCTUARY
Quests - I spent 12 hours with a friend trying to figure out how to view my active quests. I had a relationship quest active and didn't want to do it. Eventually I found that it was part of the map, and that was fine, but I would have liked to see this mentioned in the tutorial when the map was being explained.
Food - I don't like the fact that I can't choose when to eat anymore. Fable 2 I could go through the (clumsy) menu system and select a certain food, now I'm left at pure chance and can only eat when I am in combat. For those that have both Crunchy Chicks and Holy Tofu, for example, and need to be healed, they have a 50-50 chance of eating either. For the person that wouldn't conscientiously eat one or the other, it requires very frequent trips to a pawn broker to sell off unwanted foods. Not being able to eat out of combat is also a problem.
EDIT: I was mistaken for food CHOICE. When you acquire a new type of food, you can select it as your food "stash." It will constantly draw upon this when you are injured. My apologies. Unable to manually select food, change foods short of acquiring new/more food, and being unable to eat out of combat stands.
New Items - I'm not sure if this was a Lionhead decision, or more likely it was a Microsoft call, but having the butler constantly remind me every time I visit the Sanctuary that there is a Dog costume for sale for Microsoft Points is incredibly annoying. Once I visit the cross-dimensional room with the new items once, the message should go away. Remind me once every week (real time) if you like, but I don't want to be bothered to spend additional money for every new outfit. I can imagine this could careen out of control.
QUESTS
Glowing trail - I understand that the Glowing trail has always been a part of Fable. That said, I'm one of the players that have never used it. I shouldn't be able to immediately know where everything is, and magically have GPS devices on everyone. Fable 2 not using it was great. Yes, there was a headache or two, but 90% of the time it was fine, and it should be. Not all quests should be clear and obvious. Fable 3 takes that to a whole new level of insanity though. Try attempting one of the relationship quests where you have to dig up an item. "Well, I think its somewhere in Mistlake Valley..." The zones are so huge and expansive (nice!) and the dog sometimes passes up the objects, that it could take hours for a single item. Finding the rebel headquarters was also insane.
Relationship quests- I can understand that building rapport with villagers might require a quest, but for the person that wants everyone to be a friend (Not lover), I don't see the necessity to have a quest for Friend, Best Friend, then Lover. A "Best friend" quest for 25% of NPCs isn't such a bad idea, and its fine to leave a Lover quest 100% of the time. But there's far too many NPCs to make friends with everyone with the quests the way they are now, and after all, you're a Hero and everyone wants a Hero as a friend.
REFERENCES
Fable 2 has always had a strong comical side of it. I think most people here would agree that generally the comic relief is welcome. However, I noticed a few things in Fable 3 that were not comical, nor added to the game play at all, yet had implications that were not necessarily true. Note that while side quests are one thing, the following two are part of the main quest and MUST be completed, like it or not.
"The Ends Justify The Means" - which is a referance to Saul Alinky's "Rules for Radicals" book. I do not see how that helped or added to the game, and in my opinion, was used in poor taste.
The bailouts - At one point you are asked to bail out the economy, specifically the financial institutions. The choices are a) Bail them out and the economy prospers, or b) do nothing and it tanks. The fact remains that there isn't a single bank in the game. Gold is kept in chests, in the treasury, or in the Sanctuary. Its assumed that each NPC carries a little on their person, but without even a SINGLE bank in game, its simply a money dump.
Generally, so far I've had a lot of fun playing Fable 3. The weapon upgrades are a neat idea, the Sanctuary is a welcome addition. The combat feels more responsive, and the AI is much more aggressive. But due to some of the issues listed above, Fable 3 hasn't fallen into one of those "I can't put it down" games where you look at the clock and realize you've been there 6 hours when it felt like 40 minutes.
