Id stay away from Twisted Metal and this is coming from someone that was highly anticipating this new title. SP is too hard to the point that its frustrating and not fun and the MP is broken and has major balancing and connecting issues. I cant imagine it having a whole lot of people still around since its old by this point. The controls have a very steep learning curve as well. Also didnt help that Cage abandoned it soon after it dropped. I would say it was my biggest gaming dissapointment of 2012
inFAMOUS 1, and maybe God of War games
You can probably ignore everything else
I have nothing to say about War Hawk
Bad advice! Aside from whats been mentioned:
It depends on what type of games/genres you are interested in. If you like FPSs, the two big exclusive franchises are
Resistance and Killzone. Resistance presents an alternate reality past in which aliens have invaded the world in the 1950s. My personal favorite was Resistance 2, but 3 is probably the best one. Killzone is more of a futuristic intergalactic shooter. Killzone 2 has the best SP whereas 3 has the better MP.
If platfomers are more your thing, be sure to check out the
Ratchet and Clank series which is a hybrid of a platformer and third person shooter. The games literally look like a Pixar film and fused with personality and humor.
LittleBigPlanet 2 is a great game to have as it has a very robust creation system and the community has created pretty much anything you can think of.
Modnation Racers is good if you are into kart racing. The AI in single player can be a bit cheap though
Heavy Rain was my favorite game from 2010. If you are into games with a great and immersive story, this is for you. Its very unique and offers an original experience not found in many other titles this gen
Demon's Souls and Valkyria Chronicles are both great RPGs. DS should feel familiar if you've played Dark Souls and VC is a strategic RPG with an anime visual style.
Starhawk. Its the spiritual successor to Warhawk. If you like Warhawk, you may enjoy this
The Last of Us. From the makers of Uncharted and currently heralded as one of the best games of this generation. Seriously pick it up. Everyone with a PS3 should
