"Definately check out Return to Mysterious Island! And if you like that then there is also Destination: Treasure Island by the same developer (Kheops) - a game very much in the same mold gameplay wise. "
Agree, if you like first person games as well!
They're full of great landscapes!
As for
"Also would I have to play Broken Sword 1 first, I mean are the stories connected (like in Runaway) or individual"
It is like Runaway , because BS 2 takes place only after a few months where BS 1 plot left. It follows the same characters but in a new adventure .
But for me, I personally played BS 2 first (I said I'll give it a try!) and loved the game, so I brought after ALL the sequals starting with the first.
I think it doesn't matter what you start with, because if you enjoy the game you usually get the sequels as well.
