Dino Run Great game.
I believe this game encompasses many of the key elements of great game design. Its got substance, bonuses, decent length, lots of replay value, action, exploration, and its also just plain fun.
I also love how the game creates its own unique universe that is very much based on the real life event of mass extinction. Just the terms that are used make you forget its a game in the traditional sense. DNA improvements instead of experience points, Time Shifts instead of traditional "lives", milestones instead of levels.
Its got traditional arcade style bonuses too, such as a combo system (dactyl chain) and gathering of points (bones) to unlock new modes that make the game harder or easier depending on your choice, and the "death surf" feature really gets your heart racing.
The game also has a sense of urgency. You really have to run or you will die! And you are the only one who can save that poor dino's life. Its also interesting that no one else has ever tapped into the dinosaur extinction event for a game synopsis (that I'm aware of).
I was thinking that this would make a great game for WiiWare and 360 Arcade. Charge a small fee for the console version and include the hats and donation bonuses with it, so that the price is fair to PC users. And the possibility of linking the multiplayer from the Wii, PS3, 360, and PC version to all be compatible with each other would be great! Its a possibility I suppose.
