Anyone else remember the two Everblue games for the PS2? They were developed by Arika, a company more famous for the Street Fighter X - series.
The Everblue games were basically scuba diving simulators with some basic RPG elements. They were incredibly immersive, at least the underwater parts. The land-based parts consisted only of semi-static 2D images of town streets, dotted with civilians and shops with whom you interacted simply by clicking on them.
The point of the games was to explore a number of sunken vessels, as well as the sea floor itself, in search of treasure. Each game offered a huge, breathtakingly beautiful underwater world presented in vivid color and detail and, unlike the town screens, done entirely in stunning 3D.
Now, everybody in town would invariably ask you to find SOMETHING for them, be it some lost luggage from one of the more recent shipwrecks, or a complete collection of all antique swords that could be found in the game. In short, no matter WHAT you found, someone would want it. And the only way to get 100% completion was to provide EVERYBODY with EVERYTHING they wanted. So, whenever you'd found some new type of treasure, you had a choice of selling it for money - or GIVING IT AWAY for bragging rights!
Yeah. "Wow, that painting is worth $13 000! Can I have it?" "Sure!"
I couldn't help but think about how much it would suck to be the protagonist at the end. "OK, it has taken me ages, I've been regularily chewed on by sharks, poisoned by urchins, gotten lost in claustrophobic, maze-like wrecks and been inches from death more times than I can count, but I've finally drained the ENTIRE OCEAN of valuables! And given ALL of them away, leaving me with nothing but the shark-gobbled wetsuit on my back! HOORayyy... um... Wait, what?"
(OK, most of the stuff would respawn, but still...)
