I find the worst offenders to be the demos that take place in a wholly different area that does not exist in the full game. And they have features blocked off with a "Get the full game!" plastered in place. You want me to buy your game but you're hiding what the heck it's actually like with this demo, well, guess I won't buy the game. I miss the old shareware method where you had an entire episode of the game for free and you had enough content to get a good idea how the rest of the game will play.
