I really liked those. There was no actual boss or enemies to fight, it was all about survival, healing people, making sure their body temperature is right, and all of that. Also if you liked the scavenging and survival part, there's this long running series of games called Lost in Blue on DS (with a console version for the Wii). They're part of this earlier series called Survival Kids on GBA.
Basically you're shipwreck on an island and have to scrounge for supplies, build tools and weapons, set traps, cook, manage your thirst, hunger, and energy, and explore. It's a lot of managing your time to make sure you can explore more of the island and unlock its secrets and find other survivors.
