It's always Rodeo Machines.
OH NAMCO, THIS IS THE REASON I KEEP COMING BACK TO YOU~
quick summary of the game for philistines: You're a faceless producer who takes one of these incredibly nubile, cliched and young ladies to sculpt them to do your bidding/ULTIMATE IDOL THINGS. It's alot cooler than it sounds+there are dating sim aspects in there as well.
For a purely anime style game, the motions are incredibly fluid. They weren't this good in the previous game, but damn. +This song is SOOO much better than the original (annoying) theme, The Idolm@ster.
I'm not too fond of the way the new girl looks-or the fact that her and that boring chick Chihaya bumped off Ritsuko and Ami/Mami (..I can't remember DX) as Haruka's stage partners for a moment. Though the fuckwin trio of Makoto, Azusa and Yayoi totally made up for it.
GOD HARUKA YOU'RE SO FUCKING CUTE LET ME SQUEEZE THE ADORABLE AVERAGE GIRL IDOL LIFE OUT OF YOU
Because I love you all (and the Idolm@ster site took them down) I am putting together all of the previously available flashes of the girls! They show the info card, short demo song and all of their (default- ie the ones you didn't put together) outfits~ I also included the original game trailer. Actually, Fun tidbit: The individual girl clips are extended versions of their parts in the Trailer! Good fun.
