Whether INF will have a story with interesting characters or not is irrelevant; people will play Inferno regardless. Whether the community approves of our style is their business, and we will of course take their considerations into account for future releases. But Inferno will still be widely enjoyed despite all that's wrong with it.
Just for the record, we would love to have a fancy and memorable story with characters possessing complex psychological profiles. But however, we have many factors why we just want to whitewash the most hackneyed story over our campaign; perhaps the main factor is TIME. We do not have TIME, unless the Community votes unanimously to wait for another 20yrs+ for INF SCP to be released. Personally that would break my heart. Ergo, albeit our project will lack the bells and whistles when we release it (hopefully in the near future), we will nevertheless release it simply on the basis that the Inferno name is still good and thus people will still play it. After that garners enough interest, we will add a more complex storyline and implement characters and get some voice acting done.
And personally speaking, we don't have many people dedicated on the team right now. And most of all, we do not have people extremely talented in the field of humanities and the arts to write something like that. Personally I would write it, but I'm a physician by trade (currently on sabbatical) and have zilch of a clue of how to write a convincing story.
