Entirely depends on how you like your racers. Ones super arcad-y and ones more of a simulator.

They're totally different games. Also depends if you're referring to the series as a whole or the first game in the series.

One is a sim racer that came late in the consoles life, so it took better advantage of the hardware, bigger budget, so more content, etc.

The other is a port of an arcade game. Its a launch title, with very, very limited content.

For me, I get tired of Ridge Racer after playing it for a sitting. GT is the kind of game I can sit and play over the course of a few sittings and try and unlock cars and see more of the game.

But now if you're talking about the series as a whole, then were talking about R4. I could play that all day. I much prefer the arcade style racing to the sim style of Gran Turismo.

Regardless, I think you could say racing game enthusiasts were eating good on the Playstation back in the day.

Ridge racer.

They are very different, not just between the two but even between the different iterations of each. They compete but not directly.

They're very different racers. One is arcade racing, drifting fun perfected, the other is an incredibly fun racing career and car collecting simulator (still not an actual simulator, but physics at least resemble the real world)

I say play both GT2 and RR Type 4 and see which one you like better. Alongside Wip3out I'd say these are the absolute BEST racing games of the console.

A game with a huge number of cars and tracks along with and in-depth progression and upgrade system vs a game with only one track that was so simple that they whole game could be loaded into memory at once?

They can both be fun and are kinda different but GT imo is much better as there's way more to progress through. More cars, more tracks, more options.

Very different games but I would say Gran Turismo is better.

I do like Rage Racer more than both of these though.
