It's not that it's a rhythm game, in fact it looked a lot like Theatrhythm Final Fantasy gameplay wise which I liked. I'll give you the perfect comparison though. When your husband goes out to buy you a ring, what would you want? A diamond ring or a zirconia? However, in the case of Metronomicon, graphically, it's more like a diamond ring compared to one made of dog shit. The character designs, everything just looks stupid as crap. I'd honestly rather play that homebrew PSP rhythm game that's pretty much a ripoff of DDR.
And obviously you know my opinion of those Kemco RPGs. "Most" RPGs are worse now than they were in the past yet the Kemco RPGs are even worse than those. The ring thing would work for Kemco RPGs as well, but obviously based on everything about them.
