"The Achievement system on XBox 360 was an evolution, allowing players bragging rights for their efforts in gaming overall. People want recognition for their gaming, for this reason Sony followed Microsoft's lead with the Trophy system, even Quake Live has an achievement system; Rewards (hereafter all systems are referred to as Rewards.)
There was a time that I was happy with my save file, knowing that the info of my efforts were contained therein. But today I need to have the Reward for 'Story Complete' and 'All Jumps Completed'. Almost like monetary compensation for employment, games need to give something other than the enjoyment of a hard days work, back."
