I don't particularly care whether it's first person or some other perspective. Whether it's a shooter (or some other form of combat) isn't really relevant to my point either.
Open world yes - that's totally an ingredient that goes in there.
Storylines rather not. The thing is that storylines are pre-written, canned content that's just identical for every player that consumes it. In order to fit my bill, the "plot" of the game would actually have to be defined by what players are doing (and the game simulation reacting to that) - it would have to emerge dynamically. Saga of Ryzom originally tried to go a little bit along those lines, but due to the technological constraints of the day, the game world would have to evolve through updates/patches mostly.
The issue with SoR was not really technological constraints. More budgetary and time constraints, and the people who had the creative vision left shortly after release.
The commercial game is now run by a finance guy and a web developer, pretty much. Neither of which seem to be interested in pursuing the original more daring vision.
The tech is definitely capable of being expanded into a real dynamic world.
What you see in the game right now is effectively auto generated placeholder content that got rushed in to have a deliverable by release.
Imagine if the tribes and mobs actually moved their locations dynamically, instead of being in the same spots eternally. Players could help out tribes, supply routes for trading goods between tribes would need to be maintained, mob populations would be affected by player activity, etc.
