Topic: Need some advice for comms

Shortly ill be deploying overseas with the military and I promised my 7-year-old son I would buy a PS4, take it with me and play online with him when I get some downtime, and he was very excited about this and it calmed him down, as he was understandably upset hearing the news.

Unfortunately, I haven't played PlayStation since final fantasy 7.

I didn't really think about what I need until now, I have a few questions if anyone is able to help me.

1. He is logged in under my name on our PS4(family account) do I need to set up a new account? and if not will we be able to play the same game on 2 different PS4s.

2. Should I buy a new, second hand or refurbed?

3. What should I do about a headset and mic how much should I spend?

4. anything else I should know?

5. Games he plays are Minecraft, rocket league and FIFA.

Any help/advice would be much appreciated thanks .
