	Acheton, by Jon Thackray, David Seal, and Jonathan Partington 1 vote "Old style cave crawl but tougher than a turtle's carapace." [+]"Old style cave crawl but tougher than a turtle's carapace.: Acheton. Enormous game with an acceptable two word parser from Phoenix but unfairly difficult puzzles. The lamp also has a very parsimonious timer which is unforgiveable in my opinion given the size and complexity of the game. A typo also counts as a turn." ( - Full review) --Canalboy...

[+]"Possibly harder than Acheton from the same Phoenix stable. The hardest game I have ever played.: Boy is this tough. Type SAVE and you will die. From there on in the mind boggling puzzles just keep coming. Easy to put in an unwinnable position too." ( - Full review) --Canalboy... Vote for this game

	Reefer Island, by Steve Barrera 1 vote "Evocative and evil." [+]"Evocative and evil.: Having played over 500 text adventures this is in the vanguard of difficulty. It is extremely easy to render the game unwinnable and not realise it; the deceptive soft lock is the most insidious device in the history of these games. It is counterbalanced by excellent writing and clever choreography." () --Canalboy... Vote for this game

	Fyleet, by Jonathan Partington 1 vote "Another unforgiving Phoenix mainframe game. Very large and very difficult. " [+]"Another unforgiving Phoenix mainframe game. Very large and very difficult. : Everything from Marcel Proust to Hohenzellorn helmets in this one. If you have laboured long on the Phoenix canon you will know what to expect. Don't forget your prayer mat!" ( - Full review) --Canalboy... Vote for this game
