What PS3 games should I play?

I have the PS3 for about a month. I finished The Last of Us and Uncharted 1, 2, 3 and I really enjoyed it. I'm currently playing Demon's Souls because I'm a huge fan of Dark Souls.

I will list some of PC games, which I really liked.

• Assassin's Creed series
• The Witcher series
• Gothic 1/2/3
• The Walking Dead
• Metro 2033/Last Light
• Tomb Raider
• Skyrim

What PS3 game should I play next?

btw. English is not my native language. Forgive me for my grammar mistakes.

edit: Thanks for all the suggestions. I have a lot to choose from :)
