I often go looking for fan made Sins material and I decided I should post links to various things I find that I think are cool:

Here are my first three:

1. There some really cool screenshots taken by Teknopathetic during a multiplayer game on the Neogaf forums which can be seen here: http://www.neogaf.com/forum/showthread.php?s=c35d7a36c9a01b964594df6e19ca060c&t=235409&page=6

2. This YouTube video by NoSoundAvailable is from an early beta but it's always been one of my favorites: http://youtube.com/watch?v=KQ9yWrFzk9w

3. This YouTube video by antisocialfatman http://youtube.com/watch?v=jEGxNC11yPU really shows off the power of the in-game Map Designer and the Iron Engine. 250 planets spread out over 15 or so stars!

4.  I just found this one on youtube and it's an early small battle which is very well editted and shot so it feels like a neat little story. Well done SpaceSinner! http://youtube.com/watch?v=GxSGcp3Ku_8

5. Noelveiga and harvest post some pretty incredible screenshots from some really epic Sins games they recently played. You can see them here: http://forums.penny-arcade.com/showthread.php?t=20697&page=35.

6. Ok, this is the craziest Sins map I've seen so far. Argh presents MiddleInsanityUltimate: http://www.ipdclan.com/phpBB2/viewtopic.php?t=2521

7. First video review by antisocialfatman! I highly recommend this as an overview of Sins even if you aren't interested in the review portion of it. Well done http://youtube.com/watch?v=xY-NSNhgydY

8. Cool fansite I came across:  http://www.clansofsin.com Strategies, research breakdown, game features and more!
I particularly love the way the tech trees were done.
