No prob, man. It's pretty straightforward. Turn on the Wi-Fi switch on your PSP and access the Playstation Store (it's under Playstation Network). On the very first page itself, among other things, you'll see the demo icon. You'll need to create an account to download demos. That said, I think it's better to download them via Media Go which is Sony's version of iTunes. Like Slapshot said, it can take a while to download directly from your PSP. You can download Media Go from here: http://www.sonycreativesoftware.com/products/mediago/default_enu.asp?page=download Lucky you.
I tried the Peace Walker demo yesterday, it's quite impressive technically but I'm sad to see it's closer to MGS4 than the first two games, I want the radar back. I was sneaking behind a guy with a wall between us and somehow he was alerted. I'm sure it wasn't just a loud noise. Seems slightly less reliable than the good ol' "cone of sight" method.
My gaming indecision this week (aside from MGS that I can't wait for tomorrow night for): The new Pinball Heroes Bundle 2 featuring Wipeout, Fat Princess, Modnation Racers, and Motorstorm OR Twisted Metal: Head on
If you've played Fat Princess on the PS3, then the PSP version is almost exactly the same. Except for the online multiplayer, which is lacking and of course the graphics are downgraded a bit. I really did not like Modnation Racers for the PSP at all, if you've tried the demo though and enjoyed it then it might be your best choice since it has an insane amount of content. Wipeout is always good(I have Pulse), but have heard good things about Pure as well. Best futuristic racer out there. Haven't tried Motorstorm that much, so I'm not so sure on that one. Same with Pinball Heroes, though I'm not a fan of pinball on a small screen. Twisted Metal Head On is a nice game, but it's not as good(in my opinion) as the other options you have on there. Speaking of MGSW, I finally tried the demo yesterday and the graphics are amazing. Better than any handheld game I've ever seen and better than a lot of console games as well. Before it was GoW:CoO, but this game beats it in the graphics dept. With that said though, I've never been a fan of MGS games, so I didn't enjoy actually playing it.
Ehh... it looks like I'll be getting Peace Walker since my stupid Xbox got the red ring of death... Seeing as I'm trading in Army of Two The 40th Day along with Call of Duty: Modern Warfare: Reflex soon, are there any other good games I should get? I don't know if I could get the GTA games, considering language and other things (which I might be able to get by considering that it's all optional).
I was saying the Pinball Heroes Bundle 2 features each of those games with a table. There are four tables, one is for Modnation, one is for Wipeout, one is for Motorstorm, and the last is for Fat Princess. Each table has it's own rules and objectives that kinda follow the console game. There haven't really been any reviews for the game yet, so it's kind of a blind purchase. The only one of those games I actually enjoyed was Motorstorm. Wipeout was close to being liked, but I can't help but compare it to F-Zero on Gamecube, which I loved much more.
Oops, kinda of a waste my post then lol Should have read a bit slower. Sorry I'm not help on that one then.
PSN updates at 8pm EST in the US, and like 3pm EST in the UK. Otherwise it should be on store shelves when they open tomorrow.
