Rather than say the game sucks in general, I'll say why it isn't very good, for me.
I realize this is beta and use that grain of salt liberally when seeing the entire opening day scrubbed due to server connectivity issues on MS's side. I do not think it was okay to have the graphics on PC look as dated as they did so close to public release. But, I will say that even bumped up to max, the game ran very smoothly on a mid-range machine.
The auto-aim code is strong with this one. Aside from a weapon that can lock on and automatically track and kill multiple things at once, there is far too much correction going on. You can especially see this in the immediate death replays while waiting to respawn. Or when you wonder how the hell you just hit that guy when your cursor ended up blocked by the wall.
There is way too much one-shot killing. You can kill a guy with a shotgun clipping a foot. You can one-shot anyone from about 7-8 meters away with a flying kick. I'm not kidding. I topped an entire match solely (get it?!) by meleeing.
This is not a mech game. When you get your titan, you are pretty much a wrecking machine if you come across any other player. It's not that it's all just power, you also have about as much speed of movement and agility. That side-step is powerful, even with having it as two very short-timed charges. In one quick backslide I splattered 4 pilots and 4 npcs.
The npcs on each side end up making it harder to locate actual players. However it's a strange mix. The flow of combat is so inhibited by so many features that are crammed into the game. Like the cloaking ability, and the mini-map pointing out enemy locations, and the FOV being capped as it is. Don't get me wrong, those would have their places in other games, but it seems like it was about how many features from other popular games they could put in "Titanfall" rather than how they actually affected game play.
I actually really like the way the double jump/wall sprinting mechanics were implemented and that alone would have been amazing. I just don't think everything combined the way it is fits together into one coherent game.
Lest anyone try calling me out, I was really pumped for this game. I'm not an EA fan, but this game really caught my eye. The game just feels like a run-of-the-mill FPS console port with little else going for it at this point.
I will personally be passing on this game. The only other upcoming FPS that caught my eye was "Tom Clancy's The Division" and I really hope that turns out well.
