Okay, the first Fable came out roughly 5 years ago, Fable 2 less than 2 years ago, and they're planning for a Fable 3 already? I haven't heard anything about this other than seeing it on Amazon, but I'm already skeptical on what this game is going to offer that's going to differentiate from the other 2.
First off, the variety of weapons and the combat system in 2 made it unique and fun, and all of the vulgar quirks within the game kept me laughing until the end. I am hoping for more improvements this time around, including:
-A better economic system where it isn't a joke to buy out an entire town
-More exciting less tedious and repetitive job works
-More compelling side quests
And above all:
LONGER GAME PLAY
That has been my biggest problem with the Fables. I finished them in what seemed like no time and was constantly wanting more. The additions to Fable 2 were weak in my opinion and didn't keep me engaged very long.
I'll have to start checking on trailers and possible diaries to download on this game since I love the series, but I really hope these improvements come along. The open ended environment of these games is what I love about RPGs more than anything (and linearity is currently the only problem I have with FFXIII at this point in time, one of the best RPGs I have played in a long time) and if they really utilize this aspect, Fable 3 can trump the other Fables by a landslide and become a next-gen milestone. I hope they do things right.
