A portion of an OMGNintendo review...

If Game Factory ever broke up the mini-games in Rubik's World's and distributed them individually on WiiWare for 500 to 1000 points each, I could happily recommend the good ones. I could also recommend picking up either SKU if you happened to catch it on sale. for less than $20. Neither game is worth buying at its full retail price ($29.99 for DS and $39.99 for Wii) because the quality is just way too uneven.
