Okay, I actually had prepared the new training videos in time for 2.0 -- knowing how out of date the old ones were -- but I ran into some technical difficulties getting the video split up into parts so that it could be uploaded to Youtube, and so they haven't been uploaded until now (VirtualDub to the rescue, in the end). Here's the link to a new 30-minute video tutorial in three parts:
http://www.arcengames.com/aiwar_videos.php It mainly covers topics that are not otherwise discussed in the main in-game tutorials, such as demonstrating free roaming defender mode, group move, energy management, and how to recover from a variety of tactical and strategic blunders. Watch me tank my economy, get raided without defenses, fail to put up tractor beams, and more -- and see how to quickly and relatively easily get right back on track.
If you're already an experienced player, these will hold nothing for you, but the old videos were a popular supplement to the interactive tutorials, so these new ones are meant to be an updated version of the old, with more useful and up-to-date information spread throughout them.
