I'm very disappointed to here it's going to be implementing cards. I remember playing Metal Gear Acid for the PSP. I had such high hopes and then when I started playing I found out it used cards. I didn't hear much about the game so the card thing totally caught me off guard. I barely played it, only completing 1-2 missions before dropping it. I loved Metal Gear Solid, but implementing cards was a huge step back.
I haven't played Blue Dragon for the XBOX 360 yet, but I'm hoping once summer hits to pick it up and give it a try. With RPG's you need a lot of time and I don't have that time right now. I can pick up a game here and there, just not enough time for an RPG.
