This image really sums up why some images and some aspects of the Forza environment look a little 'fake' and how it really ruins that 'real life' allusion/illusion.
The blend of bitmap backgrounds into fake computerised grass with a car being showed that has really 'real' looking plastic lenses and windows and sills and overall car model, but the tyres and lack of shine and gloss feel on the bodywork really look terrible.
Its a bit hard to explain, and its easy to say simply that it just doesnt look right, but it seems a little flat and non-dynamic. Its a little too neat and hard lined, there are no real life imperfections or reflections to distract the eye from the 'too perfect and clean' car models. It almost looks cell shaded to some extent.
Why do they insist on keeping this crap 'as is' and not make any efforts to fix it?
Don't get me wrong, Forza 2 and 3 are my favourite games this gen, as I am a serious car nut and gamer, and the career and vehicle modifications make you feel like you cant put the game down, its just a little sad that visually, it does not keep pace with GT5 and the realistic material textures (even though that game lasted about two weeks for me before it got boring as hell).
This will be a day one regardless, I just really really hope they address these issues.
