Unknown column in order clause

Hello everyone! 

I've a problem returning the first row of the result set with the first() method (i suppose).

PHP Code:

Unknown column 'games.id' in 'order clause' 


This is the Migration
   

This is the GamesModel
   

This is the Games Controller
   

If a change the id filed in "id" everything works fine. 

Does It is a convention to follow?

If yes, how can i bypass this behaviour?

Thank you all. 

PS Version 4 is awesome! Great work.
