I recently ran a contest on my server. Short version of the rules: build anything you want in a 16x16 area. I was pretty satisfied with the number of entrants, and some of the builds were really damn good. I had a hard time deciding what should win. Just now I have decided:
1st Place: StarHawk, ID 3623. "Stalker II Class Attack Walker".

2nd Place: Bacterium, ID 12458. "Greek Architecture".

My reasoning for putting Bacterium's in second place: Yes, it's amazing. It just feels really... cramped. You can't really appreciate it all because when you walk inside of it you feel like a giant in a midget's house. Now don't get me wrong,
I love it. And if he enters a similar build into one of my next contests that has a large size limit (say 32x32) I think it will be a definite contender for first place. The main challenge of this contest was the size limitation, though, and I thought StarHawk's seemed more natural.
StarHawk will receive a $10 steam game of his choice. If my hours hadn't recently been cut at work (again) I'd probably give Bacterium and maybe one or two other people runner-up prizes, it was really really hard to decide on a winner.
I will be hosting more contests like this, on a larger scale. Bigger builds and bigger prizes. This one was just to see if a contest on BL could be successful.Also, please stop by my server and take a look at the builds. There are some wonderful ones, including Rusty's, Cheezey's, Banjo-kazooie's, and a few others. And watch out for another topic in the future announcing my next contest. Same as this time, the prize will be a steam game. Probably one that's more valuable than $10 ;)
