This review is worth a look-see!
It reminds me a lot of Super Mario on the N64. Difference being there are planets, not pictures or whatever was there in N64
Galaxy has really good graphics. Its strongest point. The Wii, after all is the weakest of the "Seventh Generation" Consoles, a souped up GameCube really, though few admit it. So watching the stunning visuals really warms the heart.
Its weakest point I suppose is the game is simply go from point A to point B and then point C with very little variety gameplay wise. The developers should have shook it up a bit more. Ah well, thats how it goes with big well known titles eh?
Want to know something secret? Look at the Super Mario Galaxy Poster/box-art closely. Read ONLY the letters with a small shiny star on them. Some programmer in Japan or Marketing guy in the USA is have a quiet chuckle at all of us ;)
