Here are some real life Laguna Seca videos (although youll need apple quicktime to see them).
Go to
http://www.sierrafoot.org/laguna_seca/ls040302.html first you will see two videos.
1) Depicts turn 11 through to turn 4, including the front straight and the Andretti hairpin
2) Shows turn 5 through to turn 9, including the corkscrew.
Indisputably, Laguna Seca looks far more realistic in Forza than GT4. Im not sure why people think that GT4 looks better than Forza.
Forza has bump mapping, better anti-aliasing and real time fresnel reflections. The PS2 whilst impressive for its age is simply constrained by its hardware limitations.
Sounds:
Forza is without doubt far superior. I can say this because four people I know have the cars depicted in the demos.
- My brother owns a Nissan 350Z, and Forza is far closer as to sound.
- An old friend at University owned a Subaru Impreza STI Type R 2 door import (old shape). Another friend of mine owns a Subaru Impreza WRX stock (051 plate 2001 UK). The boxer engine has quite a distinctive sound to it and I think that Forza represents it far better.
- A friend of my dads had a Evo lancer 7. Forza sounds more realistic.
Also, when I lived with my parents someone a few doors away had a 360 Modena. The Modena in Forza sounds fairly accurate in my opinion.
The problem with the sound in GT4 is that all of the cars sound very similar. It seems like they have one generic sample, and made minor alterations so each car would sound slightly different. The Corvette in GT4 does not sound like a V8. Sound has always been a problem for the GT series.
Having said that, GT4 seems to have better background noises yet we should all remember that Forza is preview code.
However, Im not going to bash GT4 because Im sure its a great game like the other GT games. It's also quite difficult to tell how good Forza will be (seems to be plagued with bugs at the moment). Nevertheless, I remember the preview code for Rallisport Challenge 2, which had all sorts of problems including slow down. Yet they were all fixed before release.
AI: Better in Forza as the cars do not seem to be following a set path.
Conclusion:
Im sure both games will be excellent and it is futile to say at the moment which one will be best.
