Play knights and dragons 

Mortal Kombat X is amazing
You will not regret the choice of getting DLC Simulator great game! (its also free)
What you need is Football Manager 2015 installed. Best thing is it never ends! You go season from season, buy/sell players and try and take you club to the highest level. It can be frustrating though if you continue to lose games,, well that's why the squad needs lot of thinking and you've got to discover the best tactic for you team. Anyway, its fun and will get addictive quickly!
