I have decided to go on steam and in their shop tick the following filters: Indie + Free to Play and i have found an incredibly addicting clicker game called 'Clicker Heroes'. After 3h in the game i have pointlessly clicked 21k times and I'm having a blast doing so.
Uh dog, just letting you know that I've been playing Rainbow Six: Siege lately. It's awesome- the gameplay, graphics and community. You basically need to have the mind of a real spec ops guy(unlike cod where u have to just shoot shoot) as it requires lots of strategical thinking.
