Steam on DigitalOcean droplet with GUI as game machine

I installed xfce and Steam on a Digital Ocean droplet with the intention of being able to run strategy games from the droplet through.

I've gotten the two above pieces of software installed, but when I try to run Steam it throws the following error "OpenGL GLX extension not supported by display".

I expect that it's something to do with graphics drivers, as droplets weren't designed to be running graphics intensive software, but can't seem to find a conclusive solution.

Here is my process so far:

1. Install 16.04 (64bit) and get it working with VNC by following this guide:

2. Install steam by doing the following: 64-bit Ubuntu

   • add the following line to /etc/apt/sources.list
   • deb precise steam
   • sudo apt-get update && sudo apt-get install steam-launcher

3. Double click steam icon and get the above error"OpenGL GLX extension not supported by display"

This is the output from sudo lshw -c video:
