Okay, the video was funny. However, I can't really agree with it, myself. Everyone is allowed their own opinion, of course. This one's mine.
I have this game and I played this game on the normal level of difficulty (Experienced). Putting aside anyone's opinion (good or bad) of what they think of the acting or the plot, I didn't have half the trouble Yahtzee apparently did. Can't explain why either.
Movement and camera manipulation was controlled by the proper analog sticks, the controls were explained well enough, and I could see what I was doing. Aiming the proton stream was only difficult in the sense of how sensitively you move the analog sticks and not that hard to get a handle on. (Plus, if you don't like the stream, just shoot it with something else!) To me, there wasn't a problem with a ton of streams in the room, since I used them sometimes to figure out where I needed to fire.
The business of traps? I've no idea what the issue is. You put out the traps, you grapple the ghost, you fling it into the nearest one. Where's the problem? I may've had to do alot of the work, but I'm the main character in this game! The other Ghostbusters were backup. They kept other ghosts occupied and trapped some of them and I did all the things they wouldn't. The reviving process didn't have any stitches for me either. I got knocked out and brought back as much as everyone else and it all worked out in the end.
In fact, the AI seemed to be totally fine in my game. Hell, there was one of the later boss battles where I did nothing but run around and look tasty so the others could blast the sucker into oblivion. If you can depend on them to kill a giant monster while you just run around, then it's fine. The only problems I had with the game had to do with some of the enemies at certain locations.
You know what it is? I think games hate Yahtzee.
