For two years, I've been a community member of and contributor to The Odin Project, and in my time there I have grown from a help-seeker to primarily a help-provider. TOP's curriculum features many opportunities to build games, from simple ones like Rock Paper Scissors and Tic Tac Toe, to more complex ones such as to Chess and Battleship.
As a Javascript developer, much of my learning happened in the browser environment where access to markup and styling is conveniently close at hand. As wonderful as this is for the process of game creation, I have often witnessed the tendency for inexperienced learners to fall into the anti-pattern of interacting with the DOM too freely within their game logic.
