For a faithful recreation it is a 5 star, but game technology has come a long way since the PS1 era and as an actual AC race course, it's difficult to give it higher than 4. You've spent time on this course and it shows well in your offering, but for a track that's been abandoned since the 90's it doesn't feel or look like it has aged one bit and that to me is actually a negative.
The track details are adequate, but hardly are they a looker. The over-sized and generally cartoon-like look of the billboards distract the driver, and there doesn't seem to be much variation in terms of tree placing.
Past that, the lack of a proper pit lane area and only 10 'pits' makes this track a bit difficult to use for anything than hot lapping and drifting. The location of the pits causes wide cars to hit the side wall.
If some work was done to the colour choices, texturing, props and race groove I'm sure this track would become a stellar modern-gaming interpretation of a classic Sim racing track.
Thanks for this and thanks for your work! A trip down memory lane... Would be awesome to see Deep Forest Raceway one day... The track is one of the smallest tracks in Gran Turismo 2 and if I remember correctly was only a max of six cars... Any more than 10 would be AI traffic jam...
