Ugh. No, I like having space on my hard drive and desktop.
That said, I can identify six games there that I have installed: Utawarerumono (a strategy RPG/eroge), Battle Moon Wars (an all-ages doujin Super Robot Wars clone/parody/homage involving TYPE-MOON characters), Fate/stay night, Fate/hollow ataraxia, CROSS†CHANNEL (the game NANACA†CRASH's characters came from), and Sengoku Rance (a wargame/eroge). I'm also surprised by the non-presence of certain highly-popular titles, such as Ever 17 (unless the Japanese version has a different icon, which is entirely possible; Ever 17 is an all-ages visual novel) and Tsukihime (as well as its sequels).
