If the PS4 had a cache of other new games available, then I wouldn't consider getting Tomb Raider against for $60 for the graphical update
However, the PS4 game library currently is pretty pitiful. When Tomb Raider arrives for it next week, it will be the highest reviewed full retail PS4 game on the system.
I mean it is a 9+/10 game, while Killzone Shadow Fall is a 8+/10 game
Furthermore, Killzone is a FPS, while Tomb Raider is Action / Adventure
I want to play Action / Adventure... like Uncharted 4, and that is not even coming in 2014... so I'll just take that Tomb Raider upgrade in the interim. Thanks
