Some stores are still selling vanilla JJ2 for CD. İm not sure why the stores dont update their JJ2 but they probably need to sell their software before they upgrade it online - unless you do custom installations of plusifier on every CD which is already prə>packaged. The cost vs reward of upgrading to plus from 1.21, 1.22 or 1.24 just isnt there for the people who sell the game in stores.
