That leaves me puzzled, I struggle to imagine the reason why anybody would actually WANT a game to become a sandbox...but well, could have been worse, it could have become one of those sandboxes with the hours of the day and the days of the week...
Honestly I have no idea, I guess it also depends on the kind of game/story you have in mind, as some devs are usually "specialized" in some themes and stuff...I have some names in mind of some friendly devs, but since I wouldn't wanna involve people without their approval, I'd suggest you to...
Welcome!(y) There's plenty of threds with recommendations, try to give them a look! As a starter, well, go for Desert Stalker and Leap of Faith, and you can't go wrong ;) Enjoy!:D
