How could a game that is also on the xbox's be the playstation killer game? I swear i never understand the meta game that goes around on these forums.
As for the games themselves, i think Destiny is a better game than Titanfall. It atempts to be more, fails, but it still delivers a sizeable game to enjoy. Titanfall is just the multiplayer section of a game sold at full price. Titanfall might be better at what it set out to do, but its not as ambitious.
