I have a PS4 with no games except Resogun... and this isn't selling me.
Still interested in the setting so we'll see.
And I have a PS4 with Killzone, ACIV, LEGO Marvel, Outlast, Resogun, DCUO, and quite a few more. inFAMOUS: SS, The Order, and Uncharted PS4 are other reasons why I picked up a PS4, regardless of release date.
I don't understand why anyone would buy a console that doesn't have anything they actually want to play on it besides one game. My rule of thumb: A console/handheld has to have at least 5 titles I'm really excited about and interested in before I drop money on it. This rule of thumb has
never failed me. I broke that rule once, and I regretted it (I bought an Xbox for KOTOR and Fable, and that was it. Loved KOTOR, was supremely disappointed in Fable)./derail.
On topic, I'm excited as fuck for The Order. I haven't played every TPS out there, so the more high quality ones the better. Off the top of my head, the only ones I've played and enjoyed were Gears series sans Judgment, Uncharted series, inFAMOUS series, and The Last of Us. Hardly genre overkill, especially where quality TPSes are involved.
The Order is still at least 6 months away. They haven't even gotten into final polishing stage yet. The game is still looking great. The only thing I noticed was some framerate issues, but that's the kind of thing that will no doubt be ironed out by release.
