I gave this game a shot based on the reviews here at Gamefly. People said if you enjoyed Pokemon Snap you'd like Afrika. I can say that that is true, and unlike Pokemon snap, you aren't limited to the train ride, you actually get out of your vehicle and observe. When you are actually playing its interesting in fun, but all the down time killed it for me. Very long load times and the save file for the game is over 300mb.
If you can handle some long load times, and enjoyed pokemon snap, this game is worth at least a rental.
