At £1.99 Labours of Hercules is the best value I've seen this month.
Not only do you get a great adventure, but you also get some education as well! Don't let this put you off, though - the Herculean myths are great stories, which is why they've lasted thousands of years.
To atone for killing his wife and children in a drunken rage, and to gain immortality, Hercules is set twelve arduous tasks by Eurystheus, King of, Mycenae. This scenario has been tried before with varying success, but the story stands repeated telling, and Terry Taylor has done a grand job.
The individual labours are each a mini-adventure in themselves, and they get harder as you go on.
I particularly liked the way in which certain actions may at first appear to be the right solution, and turn out, many moves later, to be a wrong turning. Though there are four 'orrible mazes here (I 'ates 'em!), each one is different and each one is a great example of its kind.
Well presented, though text- only and no Ram Save/Load, it's an almost faultless use of Quill.
This is one for adventure-writers (to see how it should be done) as well as players.
