It's common that a PlayStation Network game is downloaded in its demo form, for that's the way PlayStation Network games are commonly built. Most often if you happen to download a demo for a PlayStation Network game, you'll frequently reach the end of the demo where the game is then asking you to purchase the game. In other words, the game wants to know if you want to pay money for the unlock key.
In Oddworld's case, PlayStation Plus is giving you the demo in addition to the unlock key. You're given the body of the game alongside what enables you to play it in full. Does that make sense?
I understand how this works but why do you have to download the whole game just to demo it?? I feel like the demo should only be the size required for the content of the demo. Sure it is convenient that if you like the demo you can just buy the full game unlock and start playing instantly, but me personally wish some of the demo sizes were smaller. Thus far I have yet to purchase a full game unlock from a demo.
