Desktop Game + Mobile as 2nd Screen (Concept)

for more interactive experience.

+ some info (summary) display on mobile

+ some control input from mobile

+ some notification to mobile screen

------- Question ---------

How to achieve this?

my early idea : Multiplayer? ( 1 player as desktop, another player as mobile, both control by same user )

or any other suggestion to achieve this.

( i have no experience building multiplayer game with C2/C3 yet )

I did this (twice)(but using a different engine) and I did it 2 ways:

First as you mentioned, I setup a basic multiplayer to transfer data.

Second way: As there wasnt much "fast paced" action and was only for text updates ETC I simply had a web server, Database and PHP script, desktop sent data and the mobile checked and updated from the Database every 10 seconds.

Hope this helps
