If we go off off the FIRST version of XX? That came out 2002 in JP and 2003 everywhere else. Reload is the first revision after, released in 2003, 2004, 2005, and even 2006 in some countries. Then XX Slash was 2005/2006. Accent Core was 2006-2007-2008-2009-2010-2011-2012. And last but not least, Plus R was 2012-2013-2014-2015 (and on the switch in 2019). I never realized how odd the release dates were and how much delay there was but, yeah. Going off off the frst vesrion of XX it's been exactly 10 years, just like Testament.
