Mincraft was May 17, 2009… This was March 25, 2010…
Riiiight.
The release dates are (somewhat) true, but the DEVELOPMENT of Love started well before Minecraft back in 2008.
Proof: http://massively.joystiq.com/2008/10/25/eskil-steenberg-interviewed-about-his-one-man-mmo-project-love/ (The interview link posted pre-dates back to October 25, 2008)
Also: The 2009 release for Minecraft was only in alpha form and not fully fleshed out like it is today, while the March 2010 release for Love was a finished product.
