As I have written in the description, I can't remember the title but it was a RPG/Survival game similar to Robinson's Requiem and Deus. I remember you started in a desert island and you had quite a lot of possibility to survive, including hunt (there were lions, if I'm not mistaking), make tools and even build your own tree house. Graphics were quite good and, if I remembe well, you could even grow weed.

Please help me to find the title of this game!

Lions?
Could it be Stranded or Stranded II? :unsure:

Although I wouldn't rate the graphics as 'quite good', it does offer everything else.

Huh... no, it's neither Stranded I nor II, but they seem even better than what I was looking for. Thank you very much.

There is a good survival game called Notrium.You get crashed on an alien planet and you have to find means to survive .You collect varius things as you go along and you use them to make varied items.Your ultimate goal is to repair your ship and get off the planet.
