After 2 hours of playing on advanced sensitivity, I am not impressed. They weren't as bad as I thought they would be, but my reticle still moves around to much and my arm gets tired, something that you never experience with mouse control.
Yet, when I turned down the sensitivity, I just felt like I was playing with an analog stick again, in the sense that it was too slow to move/turn around. So, the issue for me is, better than analog stick requires advanced sensitivity, in terms of speed of movement.
Unfortunately, advanced sensitivity provides the speed of movement, at the price of too much imprecision. Frankly, I was getting a little dizzy, because invariably, as you move the controller aim too fast, the imprecision makes you end up moving the camera (unless you use lockon)
Also, I found the 'interactive' stuff to be hit and miss. For example, the very first thing, when you activate your ship's thrusts, half the time, it does not respond to my wiimote motion property. Other times, when dealing with the door lock thing in the security check section, you're supposed to grab the thing, pull it out, twist it, and put it back in. Well, well over 50% of the time, the first two parts succeeds (I grab it, pull it, and twist it), but pushing it back in fails, and I have to restart my arm motion. it's like it failed to recognize that I pushed my arm forward.
So once again, I am unimpressed. It's like handwriting recognition on PDAs when they first came out. Sorry, but a 90% succeed rate still isn't good enough. I don't want errors 10% of the time. The WiiMote reminds me of this.
Sometimes it works, sometimes it doesn't. But once thing I know is, my dual analog controllers *always work*, and in the days of optical USB mice, I almost never experience the mouse giving me trouble either.
I fundamentally, do not like control mechanisms with a probabilistic succees ratio of my input being recognized as something like 1 failure in 50 inputs. It's just too high.
I give them credit, since the potential of this surpassing the control you get in other FPSs like Halo on consoles, is real. Unfortunately, the implementation for me leaves something to be desired.
I'm still looking forward to the day when consoles permit mouse/keyboard combos, or perhaps some kind of knee-pad strapped trackball.
In the meantime, I made it to Pro level on Wii Tennis, and I actually like it more than my initial review.
