I'll give the release a shot, but saying now.. There are other games with in-game rendered visuals/models that are much better than this, and in your three year completion time frame those other games visuals will only get better.
Having a great story is just one component to a game. It's like if you have a great book, with a story of a lifetime in it, but the cover is torn off partially, pages are ripped and smudged by dirt, burn holes, a few pages missing, etc, all of that detrimentally impacts the story. Your visuals are already 3-5 years behind even the other moderately successful games that have game generated models (I could name the other games that come to mind but won't unless you ask).
You will only fall further and further down the list of games people flock to unless the models *dramatically* improve, but like 500% since you're already about 90% behind other major games with game generated models/graphics. Not trying to shit on your efforts, just stating the facts.
