blockland was created in 2004 while roblox was made in 2009 so if anything its the other way around, the problem, more people know about roblox
I wish blockland would be popular. Not too much though since when you host on your desktop (non-dedi) it could crash after hitting around 22-30 players, dedicated by yourself could hit around 35-50 players, but unless you have dedicated hosting, then your fine.
they lack features we have which is a disappointment.
roblox was made in 2004, too.
What videos?
ROBLOX was made in loving 2006 end of story. The Roblox devs themselves however have pushed it recently saying the site was created since 2005 (seriously?). However if you go and watch one of Shedletsky's first videos of Roblox (http://www.youtube.com/watch?v=LTnMKjXEnMY), the year the video was uploaded was in 2006 and in the month of November and it says in the bottom of the description "ROBLOX is currently in alpha and is receiving rave reviews from hundreds of real players." The game may have been under development earlier but released to the public in or around 2006.
