Parents should take note that Soul Calibur is clean and wholesome martial arts fun as far as fighting games go. You won't find any of the extreme gore popularized by Mortal Kombat. Also, be forewarned that all the Japanese dialogue (with the inclusion of English subtitles) has remained in the U.S. version. There's nothing wrong with that directly and there's even somewhat of a nostalgia factor stemming from the early days of Street Fighter 2 (which was another game that did little to mask its Japanese nuances). I was just surprised because titles today, especially role-playing games, usually go at great lengths to fully domesticate foreign imports.
A quick glance at the enormous 'Moves List' for any character is likely to make the casual gamer, who isn't into extensive research and study in the name of games, squeamish. Though many may be surprised, as I stated in my review, Soul Calibur on its default level settings is a breeze and surprisingly accessible to even casual button-mashers. But anyone who really wants to get into the depth that Soul Calibur offers needs to devote extensive time to learning all the exhaustive amounts of techniques and skills. Having an arcade stick would also help being that some moves are near impossible to execute on a standard control pad. Having human competitors to face off against goes a long way towards motivation in learning and perfecting those skills.
