I haven't gotten a platinum game yet!!!

I feel your pain. I just got my first plat last summer and still only have 2 (plenty of 100% for PSN games tho). Try Venetica...it was my first platinum and it requires no online MP since its an action RPG. Send me a PM if you decide to do so and I can provide a guide to make things a bit easier for you and tell you specifically where to make multiple saves for the game. The story branches out 3 different ways and has 2 trophies each associated with each branch (2 of the branches require a full playthrough to the end). The multiple saves can help you avoid having to do 3 different playthroughs to get these trophies.

TELLTALE WALKING DEAD (5 episodes) - easiest plat ever , just for finishing the game , i know because i never care to plat any game but this was a plat just for keeping going through the story, its also a amazing game so WIN-WIN

I need to platinum one game before the PS4 comes out. The problem is that many games require online trophies. Can you suggest a "good" game that doesn't require online trophies?

Easy Platinums:

Uncharted 1

Uncharted 2

Dead Space

Burnout Paradise

Resident Evil 5

God of War Series

Infamous

Infamous 2

Godfather 2

You should be able to platinum one or some of these by the time the PS4 comes out. Good hunting ;)

I second Walking Dead, really easy to Platinum as its just finishing all of the episodes, also I believe they are on PS+ sale right now, so good time to buy, first couple are free for PS+ users as well (or were) so you can probably try it out. I had a blast playing them

The Walking Dead from TellTale Games. Only Platinum trophy I have honestly. Just beat the game as others have pointed out. 

Prototype 2

The mayhem is fun and it took me about a solid day and a half to plat.:P

The Walking Dead all the way. You won't regret buying the game either. Download it from PSN though and never buy the disc version. The disc version is ultra glitchy and unstable.

All the first party exclusives are good options.

Double_Wide

GoW3 and Darksiders 1 are so easy to plat I platinum'ed them twice!

I am currently in the works for my first plat as well.... Bioshock Infinite I hope.Arthas045

if you plan on going through 1999 Mode, "Charge" is your best friend, and equip any gear that helps out with melee, it will take down any enemy/boss with ease

Brave

Kung Fu Panda 2 - Took me just under 3 1/2hrs to earn the plat.

Rise of the Guardians

Sly

Phineas and Ferb - 2nd Dimension

Generator Rex

Green Lantern

Definitely The Walking Dead Episodes are the easiest.  Next I would probably say God of War games, Sly 1 and 2, Jak & Daxter, and AC2.  

offline? a lot of the games have already been mentioned so i suggest

• dragon age origins
• dragon age 2
• l.a. noire (going through it right now)

Jak & Daxter HD Collection

J&D I has not only a pretty easy to obtain Platinum but it's also much fun to get the platinum in that game, when I played it a few months ago and got it it felt similiar to what Super Mario World was on the SNES in terms of fun and gameplay levels

Sleeping Dogs is fun and easy

trine 2
DmC

Dead Space is a good game to plat.  Especially if you loved it like I did.  Alice:  Madness Returns was another fun one.  Mass Effect 2 was great, though it was pretty challenging at the beginning of the playthrough on the hardest difficulty.  Hunted The Demon's Forge was another favorite that wasn't too hard.  Then there's stuff like Skyrim and Fallout 3, neither of which were hard but they were very time consuming.  100 hours for Fallout 3 and 200 for Skyrim, at least for me.  of course you could probably cut that in half if you didn't spend countless hours just putzing around and exploring like I tend to do.

Make sure you go over to PS3Trophies.org and check out the trophy guides, that'll REALLY help with getting the plat.

Easy games to platinum which do not require any online trophies at all:

Uncharted 1

Terminator Salvation

god of war

Bioshock (original)

Fallout 3 (time consuming but easy)

Easy Games to platinum which have very easy online trophies:

Burnout Paradise

Uncharted 2

infamous 2 and the sly collection.sagejonathan

Yeah, inFAMOUS 2 and the first Sly game are especially easy to platinum

I got my first one on Infamous.  I really wasn't going for it but I enjoyed the game so much and I was so close so I decided to go all the way.  

If you just want a super easy plat, get NCIS.  $17 from Amazon and about 3-10 hours to plat.  Just play through the game and you'll get the platinum lol.

DmC

cosmicwave

DmC definitely isnt an easy game to plat

I don't have one, I don't want one.. and I don't care.Dogswithguns

why would you care? it's a non existing thing, that asks of you to do tasks that don't fit into the game story, and most of the time don't fit in the game concept or feeling ; if it's just to prove you're good at games to other players, you'll be the guy with "only one plat" so it's not worth it

Lego Batman 2 DC Superheroes.  It took me about 30 hours to platinum, but I ran around a lot.  VERY easy to platinum though and is fun.

Uncharted Drake's Fortune is the quintessential platinum. It's one of the quickest, most rewarding platinum you can get. Crushing difficulty is tough at certain parts but keep at it and you'll get the platinum.XereoWarrior

This, it's straightforward and very satisfying to get.

Also go with the Sly Collection, games aren't hard to Platinum at all, but it doesn' feel "cheap" when you do get the platinum because the games are so fun.

Sly Cooper 1 Sly Cooper 2 WWE Legends of Wrestlemania LA Noire Saints Row 3 Walking Dead(TellTales version) Back To The Future(Disc version) Sonic's Ultimate Genesis Collection Marvel SuperHeroes U Draw-you need the U Draw tablet for this. But it's really easy to get all the trophies for it. God of War God of War 2 Mafia 2
