4Gamer has the breakdown on Virtual On Force’s pretty epic “Memorial Box” set. From a CD soundtrack, containing most of the music from the original game, Oratan, Marz as well as Force (somewhat rendering the rather lovely and now quite expensive Marsinal set a tad moot), the other big addition is that of a 140 page booklet chronicling the 15 years of the series’ history. From lovely artwork for each game as well as interviews with both Juro Watari and Hajime Katoki. In terms of the latter Katoki has also penned some new box-art for the Memorial Box version, something he hasn’t done for the series since the Dreamcast port of Oratan back in 1998. As if all that wasn’t enough, there will also be two Tangram super balls thrown in with the set.

It’s also become apparent that the reasoning behind taking Force to a boxed format, rather than digital download as they recently did with Oratan, was specifically because SEGA wanted to do a 15th Anniversary collector’s set for the fans. Though, SEGA are charging a premium for all this fanservice; at 10,290 yen the Memorial Box isn’t exactly cheap. If you have money to burn though, you can pre-order it here.
