R there some ps2 games which run on a CD instead of a DVD??

Question

I have been on gamestorrents.com and noticed that some small sized games are of cd quality and bigger sized games are on dvd?? Is this true that ps2 games also run on CD??

Answer 1

Especially early on, there are quite a few games which come on CD rather than DVD (like launch titles, SSX and Timesplitters.)
As they get bigger and developers spend more time on the games they needed more room and move to DVD (cue analogy to PS3 and Blu-ray....)
