I'm increasingly impressed with the quality of free online games. This one being an example in point. It's a promotional thing for Etnies Surf, a skateboard/surf/BMX/Xgames retailer (mainly clothing and footwear) and it's quite simple in construction. There's only one level that I can see and it's pretty linear -- only one or two ways through it, and the targets are in the same place every time -- but it's in a convincingly 3-D setting and the graphics are, if not up to Tony Hawk standards, then at least detailed enough to make you say, "Hmmm."
The drawback today is still the bandwidth. I've got a fairly good DSL connection, but it still stutters occasionally on this and other byte-rich content. I think that in a couple of years we'll be routinely streaming Xbox and Playstation-quality material. O frabjous day!
Warning: Music, standard skateboarding sounds, pool of blood when he hits the curb or mistimes the cars zooming through at intersections.
Use your arrow keys to steer; spacebar to jump. I think if you do it really really well you might win a pair of shoes or something, but don't quote me on that.
