Some interesting bits, but some very depressing ones (because they seem like Software Development 101, but were apparently important enough to call out for their audience):
* Don't spend all your money on rent
* Client-server is harder than just-client
* Actually test your game, and have other people test your game too
* Dev/build environment is important
* Actually fix crashes
* 3rd party tools/middleware usually suck and make your project fail
And a few
bits:
* Dev time is better spent on adding grinds than missions
* Design graphics first, then build gameplay around that
I'm not going to hold it against NetDevil that they haven't had any major successes lately (Auto Assault), because they are trying fairly different things and are probably failing much more cheaply than most other MMO companies. Plus, I'm glad to see any encouragement for companies to fix crashing bugs and have decent development and build systems.
