CinemaBlend thoroughly trashes Afrika, one of the showcases from Sony's E3 2006 presentation.
Excerpt: "I'm not sure why Natsume thought this would be a good project to publish on the powerhouse PS3, but that's exactly what makes this game not look good. In all honesty, it looks like a game that came out of the original Xbox era and would probably be suited better for the Nintendo Wii.
The resolution isn't particularly good and the pace of the game (though, more appropriately it should be called an interactive photo-simulation program) is so slow that anyone watching is forced to stare down the uncomely visuals and blocky graphics. So far, the sound seems to be extremely well done and the vehicle and environmental effects come off with great quality. However, it doesn't make up for the long load times, bland aesthetic and uninspiring atmosphere."
