E.Y.E: Divine Cybermancy is an indie action/role-playing first-person shooter video game created by the 12-person French development team Streum On Studio, and built using Valve Corporation's Source engine. It is a cyberpunk themed game based on the role-playing board game "A.V.A." developed by Streum On Studio in 1998.

Everything about this game is strange. Even the HUD in multimon is strange, all on the left hand screen. If you like strange, this is a good start.

Botanicula

Botanicula is a point-and-click adventure game developed by Amanita Design. I'm not even convinced it's a game. It's definitely point and click, and it might be an adventure, but game I am not convinced about. You click on random things until something happens, and then you ask 'was that actually what I wanted to happen?' before realizing that no, you still don't know what the point of all this even is.

On a bright note, wikipedia says that Botanicula is helping the World Land Trust to protect hundreds of acres of rainforest.
