I haven't been a PS4 owner for long but already have some games I enjoy quite a bit and a few I dislike quite a bit;
My go to games at the moment:
Rock Boshers DX: The Director's Cut
DC Universe Online (the first MMO I actually enjoy)
Injustice: Gods Among Us Ultimate Edition
Games I have already deleted off the hard drive:
Strike Suit Zero: Director's Cut
The biggest surprise for me with the PS4 is how much I enjoy the social networking features. I certainly underestimated them before owning the console. It's still early (for me) but RESOGUN may be the best game I played in 2014.
Which games are you digging so far on the PS4?
My latest Injustice Video f. Scorpion from Mortal Kombat and Nightwing (me):
*I pretty much only play on Medium or Hard difficulty at the moment. Anything harder and I'd be pwned too easily. The fighting genre isn't my strong area in gaming but I've always enjoyed them.
