Hey i am new to all this game development, and i was wondering if anybody could help me create a multiplayer/Online card game that has voice chat and a lot of other features? If you can help me please reply, if you know a site please reply but if you cant help me still please reply and give me a referral please! Thank you very much. 
P.S I am making a design brief at the moment!
A. Job Market
B. No one will explain you everything.
Wow, i didnt ask for everything to be explained to me so donāt go ahead and assume that i want you to take your time and write a book all i wanted was someone to explain how you start off, no more needs to be said if you are just going to wast my time on petty little comments like yours!
use google. We cannot give you details about everything because your question is VERY broad. Look up stuff on multiplayer, 3d, interfaces, etcā¦
Your best bet is to jump in and get questions answered as you have them.
For the voice chat there is this asset https://www.assetstore.unity3d.com/#/content/4639 called uSpeakā¦ costs $30 but does what your askingā¦
Networking is quite a big, time consuming topicā¦ I spent two or three months learning about and writing the networking system for our gameā¦ Donāt have my bookmarks on this system, But the learn section ( on the unity website ) , these forums and a quick search for āunity networking tutorialā should provide you with all the information you need in that areaā¦
Well i started looking on google and all that came up was just playing games like that it doesnt help!
or just google yourself how to make a mmo game for free
