Beliaeff provided an example. "On the show side of things, where they're set in St. Louis, it was important to them that they had a frontier feel to it. One of the things they were really interested in pursuing were horses. For us, we're making a shooter, it was 'OK, now we're going to have this third-person shooter, our game's optimizing for bipeds, and now we're going to have bipeds on top of quadrupeds?' We were saying, 'No, we can't have horses, bio-engineered horse or anything like that, because it will just kill us.' Plus, we're a per-pixel accurate shooter, and you do that and you're a giant target and that's not going to be fun."
The problem also occurred in the other direction. "What we thought would be awesome was flying," Beliaeff said. "Vehicle gameplay is so important in a shooter, and flying's real neat, so we want to have flying. They said, 'Well, on the game side your entire budget is pretty much CG.' For them, while they have a pretty impressive CG budget, having flying being a regular part of the show would kill them. So in that case, it helped where in the mythology where we've got the Ark ships exploding we created this low-hanging asteroid field, and it helped us evolve the mythos where we took something that could have been problematic and made it part of our lore and history."
