Oh no, I agree with you, the mechanics of the game are simple, and doing the combos is just as simple, I play Lilica, and even then I didn't find it that hard getting her combos down. Infact, most games are like this.
Still, a PS2 release is great as it does help people try out even more new things, sure you can learn combos in no time, everyone can master a combo in 30 minutes, but it all comes down to having the game more accesible to people, making gatherings easier to happen.
That in turn, will help the scene gather more match up expierence.
