It is an enjoyable game, and i like the deep 3D effect it really immerses you. The framerate drops though break the immersion a little bit.
Good racing game overall.
I don't even mind that RR3D is only 30fps (not counting framerate drops) because the 3D effect is so good. I love the tracks made for this game as well as Rage Racer's Union Hill District (Overpass City in the original PS1 version) and Mythical Coast. The only track I really miss is Lakeside Gate / Parkway.
