Are we really gonna pretend those games had anywhere near as much spoken dialogue as CP2077 will?
It doesn't matter. They can afford to hire 7 voice actors. More lines only means they have to pay for more hours of work.
Can they? Are you sure? Also, is money the only issue?
Let's just think for a moment about the process of recording and implementing voice dialogue.
- Casting calls for actors
- Decision-making process for hiring the right actors
- Introducing new actors to the team, getting them up to speed on the project, establishing relationships with directors, superiors, and other important people
- Actually recording dialogue
- Recording more dialogue
- More recording dialogue
- Running quality control on that dialogue
- Recording the dialogue again because it wasn't good enough
- Running quality control on the new dialogue
- Getting it implemented into the game
- Re-recording the dialogue because the game was changed
- Running quality control on that dialogue and re-recording where necessary
Think about all the people involved at all levels of this process. All the recording staff, coders, etc, involved with the recording, QC, implementation, etc. Now multiply that by 7. Not to mention the added complexity involved with having many different audio tracks for every single line of dialogue that must all be firing correctly at all times.
But sure, the only cost involved is hiring a few more voice actors...
