75k words is too much for me. I can’t write a novel-length work for that type of pay structure. I’m willing to give you 50k words (admittedly a small-size IF game, but a full game, nonetheless, with plenty of room for proper act structure) with the following pay schedule:

Treatment: $2000
3 Pilot Eps: $3000
12 Add. Eps: $6000
Launch Bonus: None

And the 10% revenue share is fair.
