Summary: Personally, I enjoy the songlist in 6th Style better, but this is definitely the version to start with. 5th Style, has by far, the easiest songlist. Don't let that discourage you, there are plenty of difficult songs on there, but the difficulty curve compared to other styles is significantly less. The first style with the addition of Beginner mode, makes the difficulty transition that much easier. The official controller is a must.
Summary: 6th style is a great way to start into the world of Beatmania IIDX. Right now it's still number one over my 7th Style due to the challenges and learning that Drill mode presents for me, the total n00b to BMIIDX.
Summary: As i'm waiting for my 7th Style to ship over... I really think about how good of a mix 6th style is! Great Features and Hardcore songs! Crazy Songs to really put your IIDX skills to the test! If you're a fan of IIDX and you're not really sure which mix to get (excluding 7th), Grab this one FAST before it's too late!
Summary: By far, the best version of IIDX out for the PS2 (all to change when 7th comes our ;)). Beginner mode for the n00bs and crazy 7+ songs like V [a], The Safari, Holic [a], Take It Easy etc. All around, the soundtrack is fabulous. If already a IIDX enthusiast, this needs to be in your collection, if you aren't into IIDX. Get into it.
Summary: Place a reservation on this title now, the more people that buy this game, the more konami will realize that this game is still worth pumping out for PS2! This may very well be the very last beatmania to be released on ps2, since the sales for 6th weren't exactly topping the charts. 7th style has a giant list of songs, about 88 of them to be exact. All of them amazing, addicting, and fun to play and listen to. Just buy the game, and buy it now!!!
