To include Voice Acting or No Voice Acting?

To include voice acting or no voice acting? 

When I first started working on WN:AC I had reached out to the original voice actors of Luka and Xander, asking if they'd be interested in reprising their roles. They both said yes! I was really excited to work with them again and to create another game that showed off the amazing talent of Australian voice artists. 

I received Luka's voiced lines some time ago, and had an initial listen which caused me to giggle and blush because it's so funny hearing the lines I wrote come to life. It's such a surreal feeling. Sadly, life gets busy, and I haven't heard back from Xander's voice actor in months. 

I came to a point where I just thought the game would have no voice acting.

But that's not actually what I want. 

I want both Luka and Xander to have their own voices and to bring to players the giggles and laughs I had when I first listened to Luka's lines. 

So, I'm tossing up between my options: 

1. Continue chasing up Xander's VA and hoping he eventually gets back to me,

2. Move on and put out a casting call to replace Xander's VA, or

3. Leave the game without voice acting. 

What do you, as the players, think would be my best option? 

I also want to end this post by saying there is no bad blood between myself and Xander's VA. Last contact we had he mentioned things in his life were hectic. And I understand, life gets busy.
