Well I was going to say that as convoluted as the PSN actually is atm, people generally follow suit via different Category's. Theres the Playstation classics, which can be just ports of playstation games regardless of size (these play on the psp also), theres original games like Super stardust, pixel junk, etc etc, then what I'll assume to be PS2 games in a few years times. They place their content more along price than size, if your offering a title (like a classic arcade game) thats simply a port and took 1 person's effort to put it on the network, they generally charge an abysmally small price ($3.99 for Wild Arms ;) ), but for the more original fleshed out games like PJ Monsters or Super stardust they have them placed at around $10, then for a game like Warhawk, which is an active PS3 game, they have that priced at $40.
I get what your saying now with the whole arcade arena type thing, but I just don't see the point of having a size limit :/ If they're going to even add classic games "now in HD!", that kinda defeats the retro feel and purpose, plus it makes it tons harder to slip in original content, much along the lines of Geometry Wars or that monster dungeon game. I mean all in all it's a pretty badass concept to have a category for Arcade style, original creation, and whatever else they put, but I just don't see the point of limiting what devs can do with the title :/
