I know you keep bringing that game up Deve, but I think you're the only one who ever mentions it. It must not have been a high water mark in gaming.
- What was the resolution?
- How many polygons did the game draw, and what kind of textures did it paint objects with?
- What was the draw distance?
- How many types of cars were there?
- What sort of gameplay features were there?
- How many reviewers were impressed with the physics? Or still are?
- Where did it sit in the food chain of other highly regarded racing games?
Unfortunately for 24 Hour Lemans it was a gem that got passed over by so many...
It sure wasn't 1080p anywhere... but it was on the dreamcast, and for the DC it had AMAZING graphics and I don't remember a hiccup to be seen... headlights flashed, cars shined, rain left a sheen on the track that left tracks behinds cars wheels you could see to follow, brakes turned red when heating up and there were decent pitting choices and a great hood view... and a real 24 hour race at leman...
The physics were not as advanced as GT, but when you put it on the more difficult settings you really did have to feather the throttle and straight line break to hold a chance... I whipped this back out shortly after I got Forza 1 and after quite a long stint of GT4 and on the advanced settings it was plenty challenging to be fun.

That's just the first handful from a google search.
It was a truly great game for it's time and sadly was passed up as the majority of the crowd it might have hit home with was squarely focused on GT.
Now look at that game... and think: That came out in 2000. We are talking when the PS2 CAME OUT. Whenever I hear of a "revolutionairy" racing games features I think back to 24 hour LeMans and make sure I have a solid base.
The fact you didn't even know about the game says a lot... I think a lot of GT (or even just racing) fans are unaware of what they are unaware of but still comfortable basing their opinions on this lack of awareness... see my sig
Oh did I also mention it released at $30?
That said, it was truly a bar setting game in all the things it did.
I can only think of four things which GT4 has over GT5:
- The number of tracks in game are fantastic.
- The wealth of race events is staggering, though this included a TON of Manufacturer Cup races.
- The used car lots made much more sense and were much better stocked, so you hardly ever had to wait long for a car to compete in an oddly restricted race.
- The economy was more collector friendly. GT5 is downright stingy in comparison.
But other than that, GT5 wins hands down. It has online gameplay which GT4 just couldn't do, and even the GT4 Standard cars look and handle a quantum leap better in GT5. Well, most of them look magnificent anyhow,

The ones I've seen certainly do. And I'm not one of those complaining that you can't change wheels on Standards. It would be nice, but maybe this - and interiors too - can be changed with a patch.
As for GT4 vs GT5 - as I have said before number of tracks/events in a car game are like the levels of any other game... limit those and it matters a lot less how many characters you can choose from. Can you imagine Mario with 80 characaters and only 2 worlds?
As for online, it was as much a matter of the time the game was released as anything else whether it had good online or not... even then didn't the Japanese one have online or something? Sure GT5 has online over GT4 but when you consider the passage of time having online is the equivalent now of supporting the dual analog sticks when GT4 came out... it's nothing special and to do it as poorly as GT5 has so far is actually kind of embarassing.
If you compare directly to each other GT5 is ahead in a lot of departments, but when you compare based on the time the games came out I think GT4 was FAR superior time adjusted to GT5...
I mean it pushed 1080i on PS2 with solid 60 FPS (BTW I am surprised how many around here now dismiss 40 and 50 fps as being almost indistinguishable from 60FPS when not long ago 60 FPS a la GT4 was the only way to go with racing games... I think Kaz even said how important it was himself?). It offered split screen and lan play that was pretty much perfectly executed, almost all the details felt in place, truly polished and while it suffered the same clunky loads and redundancies they actually felt less offensive then and out of place (maybe load times were just more common and acceptable then compared to now that many games strive to have no load time like Fallout).
GT4 supported a built for the game FFB wheel with paddle shifters and sequential... GT5 supports a... built for the game almost duplicate wheel... not even a clutch or stick shift in the new wheel for GT5? In order to get those features you have to get a wheel not officially supported by the game or system and thus lacking in other areas...
No... on almost every front, time adjusted GT4 beats GT5 and on some fronts like content, depth and polish you don't even need to time adjust.
GT4 was MUCH more the innovation that GT5 and GT5 has very little if any true inovation... while it brings a lot of impressive features together in one package so do many other games... and as I have said before, you can take a feature list from almost any game and use it to prove no other game "does all those things better" so it's not saying much when the overall package is just rough around the edges and unfinished.
