Britneys Dance Beat PS2 - FIRST IMPRESSIONS!!!
Well, I just completed BDB with the first character (Elisa) and I am pleasantly impressed.
It's developed by Metro, makers of the Bust a Groove/Move series, and while it doesn't have quite the same interface as BAG/M it's close. It's not quite as deep (you cant decide when to attack, you just automatically attack after every ten hit combo) the different characters all have unique attacks, and it has an option to use the DDR Dance Pad!!
It only has 5 songs though, so this might get old fast, and I have yet to try it 2 player, but I'll give you more information soon...
