Billionaire from Alegrium is all about living like a billionaire, meaning you buy properties left and right and make as much money as you can. The game is easy to get into in the beginning since it’s easy to buy properties, but once you make a million, things start to get more challenging and interesting.
Fist of Fury from Happymagenta is a Kung-Fu fighting game that shows how even the simplest gameplay can be addictive if properly implemented. Your character stands in the middle of a crossroads with ninjas attacking from all sides and if you get hit it’s game over. Sounds simple enough but that’s what makes it fun.
