I hope everybody appreciates my avoidance of the obvious “Thief games are a steal” joke in that GOG sale headline, there. Anyway, yes, Thief Gold (basically Thief: The Dark Project with three extra levels,) Thief 2: The Metal Age and Thief: Deadly Shadows are all cheap on GOG this weekend. You can get them for $3.50 USD apiece, or slightly over $10.00 for all three.
It’s all part of a Square Enix promotional event, which means Deus Ex is cheap ($4.00) and so too is Anachronox ($1.50.) The double David action of Cage and Bowie is available in the form of Omikron: The Nomad Soul ($2.50) if you want to try to work out what the deal is with that game. Quite a few Legacy of Kain titles are around for $1.50 as well.
Some rather good games, then. And Daikatana ($1.50) too.
At the time of writing, the sale has three days and ten hours to run. By my calculations that means it’ll end late on Monday (Pacific Time.)
