The release dates are (somewhat) true, but the DEVELOPMENT of Love started well before Minecraft back in 2008.

(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.
