Meaning of certain options

Trist

Newbie to OpenVPN, cannot find anything on the forum or in google which help me understand what certain options are. The descriptions in the guides aren't helping me figure it out because I am dense. I will be making a server, specifically for VLAN games in those like StarCraft which will need bridging, so I am making keys and whatnot right now. First off, why should certain options such as email or city not be left blank in the certificate? What is even a certificates purpose? What is the difference between a common name and a name? Should common name be shared by all clients on the VPN? For example, Common Name = TristVPN, Name = Trist, then Common Name = TristVPN, Name = John. What is the Common Name / Name supposed to be on the certificate, the same as the build-key-server name and common name? What is an organizational unit? What should a "build-key-server" unique name be, my clients name? I feel like I am overthinking these things but my conscious isn't letting me move forward

No .. common_name is unique for every client and the server.

Yes I read that, which is actually what confused me since it said "example; your name or your server's hostname", so I just assumed all clients should have the same hostname since the server would be hosted on my machine. Then I interpreted the words "common_name" literally I guess. Thanks for answering, that was definitely the most important option I needed explained.
