I just looked at our database's and the '[Console] Sony Playstation' mdb has 1281 entries while the '[Console] Sony PlayStation 2' mdb has 1458 entries though I'm sure neither if these are complete, there were a good lot of the early games still only CD size even though they were on DVD but as bkenobi said most were DVD so the complete set would be huge. I know the PSX games compressed down well to like 300mb a disc but even if you were to get the same compression ratio on DVDs, I'd say your still talking well over the 3.5TB mark for 1500 games and I doubt if they'd compress as well as the PSX games so you could be easily doubling that figure, it's just too hard to tell.
