The playstation store is finally getting awesome.

[Bolivar]

I got a PSP Go for Christmas and didn't even bother going to Gamestop for my usual day-after-XMas buying with the money I got. I bought Final Fantasy VII, VIII, FFTactics, Gran Turismo PSP, Harvest Moon Boy & Girl, and God of War Chains of Olympus all online. I own many of the original games, too, but the fact that I can now take them on my PSP appealed to me immensely.

I feel they've already caught up to XBox Live arcade, with most (but still not all) releases coming out on PSN, a day or two tardy at the latest. But on top of that, there's incredibly interesting and unique games like FloWer and the PixelJunk series that you simply can't find anywhere else.

So yeah, with PSOne Classics, unique PSN-exclusives and all the best multiplatform downloadable console games, the PSN is definitely in its prime.

Aside from legitimate ownership, are there any differences between the downloads and the original discs?

I could maybe answer that best in the opposite - there's even a color manual you can access from a menu when you press the PS-button(on a ps3)/Home-button(on a PSP).

Basically, it's an emulator with some features. All of the games you download are the actual data from the discs you bought back in the day. Just you can access a menu to look at the manual, have save states (on PSP), faster loading in some cases (as well as a "fast loading" feature), and use smoothing on some games. The original Metal Gear Solid on a Standard-Definnition TV with smoothing turned on looks incredible.
