ua water in WoW was blue was completely stationary.. pretty much like water in mario 64 or legend of zelda ocarina of time.

to be fair, water is not that easy to render. Water is a constently moving and is not a solid object. Water is actually is a laying process. Most do the block with a duel layer top to mimic depth and ripples. Some games add darkening and dust to make it appear like you are swimimg in a lake.

Two worlds 2 did a pretty good job. I can't wait for elder scrolls skyrim. ^^
