Picked it up today, and am pleasantly surprised. I played the tutorial, first 'level' and did the first side job.
Suda and Co. from Grasshopper take their cues from Killer 7 again by thrusting the player right into the thick of it. Gameplay takes some cues from Zelda, as well as its own original spin. The motion controls are subtle, but not tiring. Grasshopper was right not to go for complete motion control. You do have to pay attention to where your Wiimote is, since their are two stances: High and Low. You'll have to coordinate your attacks accordingly.
The frame rate goes from 60 fps to 30 fps, and sometimes a little below that. Its a shame really, but not too detrimental. Colors are bright and vivid running in progressive scan.
The audio makes good use of Dolby Pro Logic II if you have it, but stereo is fine. And yes, the first time Silvia called my wiimote, I was taken aback how it vibrated, and how she began to talk when I put to my ear. The voice acting so far is over-the-top, but thankfully not so-bad-its-good. Silvia's faux French accent makes it difficult to understand her at times, but there's subtitles if needed.
Its presentation so far will definitely bring a smile or chuckle to gamers who've been around since the pre-NES and NES era. Also, Suda's brand of humor and odd-ball style are front and center, which judging from reactions to Killer 7, will be take it or leave it. Saving on the toilet FTW.
Those waiting this long this already have it, or will get it shortly. As for the rest, rent it first, see if No More Heroes is right for you.
