I for one enjoy collecting treasure and other similar stuff. Must be an expression of my subconscious greed :P

Or perhaps it is related to the games I grew up with - they were more arcade-ish in style and collecting bonus items was a very important gameplay element. They would range from the usual valuable stuff (coins, gems, money bags, etc.) to things like machine parts, weird fruits, soda cans or books. I remember a game that had more than 20 different collectible items.

Flight sims can be very different depending on the control method. The stealth fighter game is keyboard only, for example, which feels totally different from the space sims, which are primarily controlled with the mouse (or joystick, if you have one). Space sim is easier, overall, due to the lack of gravity and the fewer objects to crash into.

Today we have "Achievements", which are an evolution of the old score system. The basic idea is the same, though...
