This is, in my eyes, still the gold standard for home Project Diva releases. It was free to play (with a very limited song pool) and had easy to access, reasonably priced, content-rich DLC packs and additional DLC after those releases. It's been surpassed by Mega Mix+ thanks to modding, but if this is the only game you have access to you basically have the premiere console version.
i do not like the arcade style of project diva game as much as the traditional style, and it being a home console version of an arcade game means it has less extra stuff than the others. The only plus this one has over the others is the fact that it has every song(Except the X ones because screw me I guess)
