Let Games generate and parse game links with custom parameters that player can copy and share

link in the form of launch.crayta.com/play/gameid?key=value&key2=value
On user login the game would receive a table with the parameters of the link used.
Some games may also support links who start a specific world without loading main one.
e.g. launch.crayta.com/play/gameid/worldid?key=value&key2=value
This may unlock many game and social mechanics like:
Sharing random seeds.
Earn something in game referring people.
Teleport in specific game locations.
Challenge links.
