Should i get a DDR game and which one should i get? (which one is the best?)
Ddr
Well, if you want a cost-effective one, you can get DDR for the PSX. My sister and I have been looking into one, and it looks like a fairly safe bet.
Otherwise, I'd definitely look into the PS2 Version. While I don't know a lot about the whole DDR / PS2 / Dance Pad setup, I can definitely tell you that it's highly enjoyable, and great exercise, and fun for the whole family and the hamster. Do invest in some. 😉 We rarely spend money in my family, but we're getting the cheapest kind.
