Are these videos still usefull?

Those videos do not get much into the code of the engine. They can give insite on how the game was programed and ideas on how to program your own. For me it was good to see what I was and was not doing in line with other programmers.

We certainly have some plans to do some webcasts of our own, (late september with more details coming soon) but right now we're just focusing on getting the beta out to you :-)
