First, you should research how much voice actors actually make for games. Unless they are some huge name they are not as expensive as you think. The charge by the day. Second, that is YOUR opinion about reading in your head etc. That was fine back in the day but not so much today. I think your making a mistake associating YOUR personal play style with the majority of players today. There is a certain production value that is expected.
I mean I respect you have your own opinion, that you just don't want that much voice work. But you can't expect to speak in regards to what the cost factor, production factor etc and try to turn that to your advantage. The average pay for a lot of voice actors in the industry make around $200-300 per hour of voice. You have any idea how many sentences can be read in an hour if the VA is prepared and is familiar with their script?
