If you want to get hyped buy the Uncharted Games for sure and Killzone 2. Those games will blow you away. When you're ready for the subtleties of the PS3 pick up Demon's Souls to blow you away.

Fixed.

In all seriousness, great game though.

also if you love RPG's make sure you try out
1. Demon Souls
2. Valkyria Chronicles
3. White Knight Chronicles
4. FF XIII
5. End Of Eternity / Resonance of Fate

also watch this awesome trailer for uncharted 2, the best game on ps3 so far IMO that is(beware of internet lag, it does not have any lag on PS3:p)

I have a PS3, Wii & an Xbox 360. To b honest, my PS3 catches dust like crazy! I play my Wii purely for Super Mario, and the rest on the xbox. If the Blu-ray movies were cheaper, I wud fire up my ps3, but I cnt afford to cash out money on blu-rays, I just settle with my Sky HD with anytime and the movies package all in HD, so why waste my money? If im that desperate for a new release, I always have the Instant-On Zune Marketplace. But thats me being honest with my console lifestyle, not bashing, but thats just the way it is in my household. My PS3 is basically a mantle piece!

you know that is clasified as trolling right?? that's the same as me saying i have an x360 and ps3 and a wii (which i do), and trust me the x360 gathers the most dust out of the three, he asked which games to get, not for anti-hype, stay on topic, as i am not afraid to report you.

that goes for anyone else who wants to turn this into a console war.

Edit: i just read you comment history, stop trolling!! you have put loads of negative comments in ps3 forums.

Nice list, I own 21 of those titles you mentioned, all great games :)

Another good two games if you haven't played yet are Bioshock and Darksiders

Close to agree with your choices but i have made changes to the list a little for my choices

You absolutly MUST buy Uncharted 2.

Than you should take a look at Uncharted 1, inFamous, LittleBigPlanet, Killzone 2, Street Fighter 4, Metal Gear Solid 4, Demons Souls, Valkyria Chronicles.

Yeh as I was looking through the Shooters list I forgot BioShock. Thanks for adding that. Yeh I think Darksiders and Bayonetta should be in the Action/Adventure as well.
