Who doesn’t like a free game? They’re quick to install (usually), they’re short and sweet, and, well, they don’t cost a penny. If that isn’t reason enough to at least try out a free game, I wouldn’t know what is. In my own experience, I’ve found that in this department, platformers do the best work. Whether they are 2D or 3D platformers, free-to-play games flourish with tight controls and clever design instead of big budgets.
