It is all a matter of perspective!

Also Bens  take on resistance is a little lopsided the campaigns are good, but the multiplayer easily is worse than Halo's. Still I think people like to over exaggerate their shooter of choice.

I recommend resistance if you like shooters. If you have a 360 the best shooters reside there, really. The KZ3 shooter experience is the king on the PS3. Resistance 3 looks promising though.

I have played all the resistances, killzone 2, Halo 3, Gears 1 and 2.

I have a lot of experience in fps so I will give you the description of resistance:

It has better weapons than Halo. Weapons are its main attraction, unique one's like marksman and its secondary attack, time-pausing sniper rifles, and grenade launching carbine along with something like a flamethrower but different.

Resistance is a very old game though and you may not enjoy it. And no imo resistance 1 was better than killzone 2.

Resistance 1 is kinda similar to halo and killzone is kinda similar to gears. Even though people compare it the opposite way.

You may want to keep off playing resistance 1 and 2 because playing them again might not be to your taste(since 3 is coming out this year and you will have a huge backlog, plus resistance 2 is not that good even though it has good gunplay).

But you should definitely get killzone 2 and play it before playing killzone 3 lol, its still one of the best looking shooters, and is worth buying almost for that...although it has a call of duty-like campaign with more special effects,  and in an alien world. But its much better, for eg. you can take cover in first-person which is kinda cool.

you can fill your boots with all those greatest hits plus valkyria and demons souls

oh and welcome to the world of ICO and friends,must play when that HD collection comes SOTC for the world

They've already been mentioned, but figured I'd add my opinion...

MGS4, Uncharted 2, inFAMOUS are my #1,2,& 3 favorite games of all time, (in that order); so I recommend them the highest. MGS4 tends to be a game that people either love or hate. I think a great majority of the ppl who play it love it, and often consider it the best game they've ever played (as I do); however, I think it just depends on your personality and preference, bc as I said, there are others who don't like it at all. I personally think it's the definition of a masterpiece.

As for the Resistance games, your cousin may not like them, idk bc ppl are different; but, I think Resistance: FoM has a great campaign (besides in terms of character development). I rented it when I first got a ps3; played for an hour or so, then took it back and bought it instead. I really enjoyed it, and the variety of weapons is fantastic. Not to mention the fact that you can play the campaign split-screen coop. I don't get into online multiplayer though, so I can't comment on that.

As for Resistance 2, I personally was disappointed in the campaign. There are huge bosses and some epic moments, but the gameplay and graphics weren't as good as R1 imho. BUT...as BenVTrigger mentioned, the online 8-player co-op in R2 is awesome. At first I didn't think I liked it, but as I played more and started working toward my upgrades, I fell in love. It was the first time I had EVER become interested in a game's online mode. I still consider my $60 purchase of R2 worth it bc of the coop.

Other excellent games:  Ratchet and Clank: ToD (much better than ACiT imo), Heavy Rain, LBP (but I think you said you don't like platformers), Motorstorm 1 (awesome, intense gameplay - and I don't usually like racing games; M2 has 4-player split screen, but it took a leap backwards in terms of gameplay imo).

Hey how many exclusive PS3 games have demos on PSN?

8thed!

along with demons souls and MGS4

i dont really do downloads but one ive tried is the valkyria chronicles demo and the game is really good, havent got around the buying the full version yet.

Killzone 2 has one.

I think god of war 3 has a demo..

One question : Have you played Gow 1 and 2? If not you can get them cheap and just speedrun through them in 5 hours on easy for both trophies and the story for God of war 3.

LBP2 has a demo if you want to try that one out.

Infamous has a demo(100% sure of this because the demo made me buy it.)

I am not sure about Uncharted 2 but it doesn't need a demo its a great game anyway.

I think UC 1 has a demo too never played it.

MGS 4 and demon's souls have no demos but I think you should try this games out. Be prepared to put a lot of time of your life into a game when approaching demon's souls.

Not sure about resistance 2.

One good feature about the PSN is that you can search for stuff that you want on PSN through the search bar. Just type in the game's name and you get stuff related to it under it.
