The real Philip Island is a great race track - a classic.
This GSCE version is not great. The graphics are substandard compared to original tracks with jaggies which can put you off as it is especially prominent on the white lines of which there are plenty. Here the AI are way off the pace at 100% (typically at 100% on all the original tracks I - an average driver - can run with them and maybe get pole by a few tenths) but these Philip Island AI are about 2 seconds down on my pace.
The only reason I give this rating because the black stuff, the actual track, is driveable and feels good. The track flows nicely and the elevations are really challenging. Verdict: shame this great track is not of the high standard of the originals because it deserves to be better in GSCE. Nevertheless I keep it on my harddrive because the layout is so good and hope the OzV8 addon coming soon might also have this thrown in as a Reiza original...
