This was/is one of the best puzzle arcade games IMO. I love it. The XBLA version adds new modes, and on-line play. On-line isn't perfect, but for me that was an ok wavering point as I love playing against the CPU or a human next to me so I can talk smack and drown the in blocks with them knowing it's all in fun. If you don't d/l this now or eventually....well just throw out all your games and clock out, you lose.
