Wave Rave:
This is similar to the old Wave Race game from Nintendo, but with much better graphics. If you've ever seen Aquadelic, this game is similar except instead of jet skis you play with power boats; in fact it's created by the same developer. :) You can see a video on the games Desura page (couldn't find one on You Tube; though I'm sure there will be some soon. This was only put up a few hours ago. The developers started playing around with better water rendering techniques shortly after aquadelic was released back in 2007, but the game created was too graphic intensive for the older computers from back then so the project was shelved. The game was never completed, but the developers decided to ressurect the game in the form it's seen today as a free game. Aquadelic is a much more complete game and can be found on Desura as well, but there's a small price tag on that game of £3.99 (~$6)
Go crazy on a jet ski in this simulation featuring unprecedented water effects and dynamics! Race courses against opponents or ride wild in a free style mode. Free demo of our shelved project exclusively on Desura.
You can get Wave Rave from Desura for free HERE. You do need the Desura client installed before you can download the game.
