Fable / Fable: The Lost Chapters
The name "Peter Molyneux" has come to be associated with hype and disappointment. One might even say dishonetsy. And thus, heavily associated with the Fable series, tainted their reputation.
Nonetheless, the first Fable game he developed with the now closed Lionhead Studio/Big Blue Box was one of its kind.
A 3rd person action-adventure with RPG elements and a moral system that unfortunately didn't live up to Molyneux's vision.
As a young boy living in a small village by the name of Oakvale you head out with the quest of finding a birthday present for your little sister. Although, the peace of the fairy tale-like village doesn't last: bandits kill your father and set everything on fire.
Fable is easily one of my favorite video game series. Nevermind the nonsense of hype and sad excuses Molyneux spouted. The games are far from perfect, they all have their flaws and shortcomings, even wasted potential. But still, the charming fairy tale-like atmosphere, the amazing voice actors in the 2nd and 3rd game (John Cleese, Sir Ben Kingsley, Simon Pegg, to name a few), they all make up for the disappointing stuff.
As for the moral system: as simple as it is (the choices are rare and obvious), no matter how often I've played it I could never bring myself to become evil (well, except to get one special weapon, but then instantly do everything to become good again).
I'm absolutely biased. I can't compare it to other Action-Adventure/RPGs. Maybe some of you too have games that can easily be labeled as this genre or that genre, compared to other games that are similar to them. And still you'd think "no. this one is different cause it's special to me". That's how I feel about Fable.
For those of you who don't want to play the game on the original XBox or the aged PC version, there's Fable Anniversary Edition. A graphical overhaul - and an amazing one most of the time - , but still far from perfect (some even say it's a schlimmbesserung). Wait for a sale on Steam. I'm a fan of the series (and a cheapskate), but I don't think it's worth 32€.
