Depends how much of a game your game is. Visual Novels which contain only a minimalist sense of game design (ex: Visual Novels) do better with more story emphasis. Others like strategy games do better with more refined gameplay, story being a pleasant but ultimately unnecessary secondary addition.
Also, keep in mind storytelling for video games is different from other mediums. You can tell stories
through gameplay. This War of Mine does an excellent job of doing that, by forcing
you to make decisions about what you're willing to do to survive and keep your loved ones safe. Do you kill the man hording food who is trying to feed his daughter, thus potentially risking your own life and the lives of those depending on you should you find nothing else after? Either way it's a story decision, triggered not by scripted event, but by what you choose to do. Starcraft I also does an excellent job of that through
music and gameplay styles. The Zerg are a constantly evolving rush-force that
feel as such in gameplay. The Protoss are slow and methodical, each of their units stronger than most others within their comparative area, but which cost more food, so your armies are always a little smaller than the others--every unit feels like it has more value as a result.
Video games are also an extremely visual mode of storytelling. You can have your games tell a lot about the worlds they're in without having a single line of dialogue or narration talking about them.
Finally, it's also a medium that hasn't
quite nailed down how to consistently tell solid stories within itself yet. It's got a ways to go still, it's still maturing and learning. So keep in mind that nobody yet knows
all the answers about it.
... Erm, by that I mean that
storytelling is not the same as
writing, though they're related topics. My skill set as a story teller in role playing
can carry over ideas like plots, premises, themes, character archetypes, tropes, et cetera. It, however, will not prepare me for the vast gap difference in how writing the stories is actually handled. (Video game writing is like, 90% editing, and a solid half of whatever you write will end up on the cutting room floor, never to be seen by anyone. Meaning your stories have to be highly modular too.) It's why most role players who write their first novel create complete fucking trash (assuming they even finish it) on their first attempt, no matter how much experience they have with RP writing.
It's an important note because it explains why so many novel writers have hopped on over to games, made an attempt, and created a defunct piece of trash. Even if their own novels may actually very well be passably entertaining.
