I've played the beta for Titanfall. It's an FPS and it's awesome.
However, I am still horrible at console FPS.
Titanfall looked very intriguing....until they announced it was 6 on 6 with bots making up the rest of the playing field.
Bots in a MP shooter = FAIL
It still could be great being as it is the work of the guys who made the legendary MW1, but I am not a fan at all of bots in an MP game, especially a shooter.
Also, if you still plan on getting a PS4, I would wait for the rumored Infamous bundles that are coming out next month. Word is that Amazon is gonna sell it at a discounted price, so you'd be getting a PS4 along with a great PS4 exclusive for less than you would if it bought it in stores.
