Impressions time!
"Show me the money!"
Oh wait, not those kinds of impressions. Kinect game impressions!
Kinect Adventures
A fitting pack-in title, as if it were sold alone I don't think it has enough to warrant a full priced title. I'd set it's retail price at $39.99. Anyway, as for the gameplay and controls: it's a lot of fun! Adventures really shows off the tech well. Certain mini-games give a great idea of how the tech could be used for future titles. After playing the zero gravity floating/flying mini-game, I'm convinced that Project Draco could be really really cool. Best mini-games are: rally ball, river rush and space pop. Also, the living statues are pretty hilarious. If I had to choose from "bad", "so-so", "good" and "great", I'd give it a "good".
Kinect Sports
A good companion to Kinect Adventures. Every sport functioned well and nearly all of them were worth playing many times in the future. I had the most fun with table tennis, bowling, volleyball and track and field. Boxing and soccer were too simplistic for my tastes. They were fun, no doubt, but didn't offer up enough for me to want to play them alone. They were better suited for Live play or local 2 player. Overall, I'd give it a "good" with touches of "great".
Kinect Joy Ride (demo)
From what I played, I totally get what people are saying about their arms being sore. Unlike Sports and Adventures, which rely on a variety of movements, Joy Ride is simply arms out in front about 90% of time time. If you've ever worked out and done the arms outstretched windmills exercise, Joy Ride is like that. Gameplay is fun in short bursts, graphics are good, and the custom paint job option is cool. Still, I can't help but think the game would be way better with deeper customization (think Lego or B-K Nuts & Bolts). Shame Rare wasn't behind this one. I'd give it a "so-so" for the full game and "good" for short bursts of play. Best to skip this one.
Dance Central (demo)
The reviewers were right. This game is really good. Menus have a better UI than any other Kinect title and the motion tracking for dance moves is surprisingly accurate. I never felt cheated. The track list is small compared to Rock Band, but DLC can easily fix that. Gonna give this one a "great". Here's hoping the Michael Jackson one is as good.
Your Shape Fitness Evolved
The demo was really short on options, only block punching was available, but it was a very crippy (trippy+creepy) interface. Rather than a cartoonish avatar, I saw my body in the game, complete with a mapped live video skin of me. I played around a lot with this, and it read everything from spinning to lying down. I even grabbed a magazine and the game read it as an inanimate object rather than a part of my body. Crazy stuff. Block punching was fun, though I can't comment on the rest of the game. But I was impressed. Oh yeah, and the movement ratio was very close to 1:1.
Sonic Free Riders
I won't say too much as I have a review to write, but it's a fun game. Not "omfg amazing", but it's as fun as playing a game of Ollie King at the arcade. Motion controls were accurate. The key is to be far back enough so that the game can see your feet (most Kinect titles track your legs, but I feel that Free Riders relies on legs AND feet). Also, to effectively turn you have to turn with your waist AND arms. The difference is almost night and day. my first race I placed 2nd, my second race I placed 1st. My first online race I placed 2nd. I will say that it is the best Riders game I've played and unlike the first game, I actually feel the need to complete it.
Overall: Hardware is there, it's the software that needs improving. Even so, if one is willing to get in on Kinect early, there are enough titles to hold one over until the more "hardcore" ones arrive. Best bets are Kinect Sports and Dance Central. SEGA and Sonic fans should try out Free Riders before buying. Kinectimals also looks to be a good title. I may just pick it up due to my love for bizarre games and the Dreamcast's Seaman (not semen, though if the Dreamcast had semen it would be pretty awesome as it could make baby Dreamcasts).
