Hey, guys! This is my first post, so be kind if this has already been mentioned elsewhere.
Unless you're going to be cribbing text directly from the previous MoO games, you're going to have to allot some time for writing/editing game errata, i.e. in-game text. Errata includes everything from game story to tech descriptions, and is a lot more work than you'd think. AI diplomatic responses alone could cover 20 pages even with a one-response-per-outcome scheme.
If you are not copying text from previous games, you will need at least one English Major type to write and edit text, because programmers tend to be, ahem, slightly less profficient at grammer and spelling.
The nominal way to write text would be to have someone write as development reaches the appropriate stage, e.g. ground combat text at v.0.6, espionage at v.0.7, etc.
My hopes are up for a true successor to MoO2!
This stuff is pretty much what I do. I'm much better at creative writing than I am at, say, generating the tech tree (as seen in Aquitaine's procrastination of the production thread).
At any rate, I run a Project for Interactive Fiction
, am in the process of trying to sell a screenplay, and was an English major.
That's not to say my writing isn't crap, but as far as the technical side of it is concerned, I think I've got us covered.
