Online PS3 with decent sized community??

So I am trying to find a PS3 game to play online. Right now I am looking at Diablo 3, Battlefield 3 or Uncharted 3. I really wanted to get into Star Hawk but heard its dead and not too good.

I don't want to play Call of Duty or Battlefield 4. Suggestions would be much appreciated. Thanks!

The Last of Us

I would say Battlefield 3. I prefer uncharted 2 multiplayer over part 3.

You could also try killzone 2 (not sure how many people still play)... or 3.

I'm sure you can find lot's of people on Diablo 3, tho most will be high level characters.

Soul Calibur 5, tho not as good as the previous ones, isn't to bad online. KZ3, Blazblue Continuum Shift Extend, Soul Calibur 2 HD remake, Street Fighter 4, Minecraft, Terraria, WWE 2K14, Tiger Woods PGA Tour 14.

Weird enough, I could not find a game within the Uncharted 3 online servers. I'm not sure if people are still playing it or it's an issue with my internet connection speed. Totally different genre, but you may take a look at LBP2 online community. It's still very active.

The Last of Us, seriously. The multiplayer is really cool and if you have a few other people to play with you can dominate. I still go back to it and I have a ps4 now. lol
