Super Mario Galaxy vs. Halo 3 - Which game will sell more units overall?

[Parokki]

Seeing how well these two titles do is going to be extremely interesting.

The userbase of the Xbox 360 is almost entirely composed of active hardcore gamers who like online FPS-type games, and even now the best selling game on the console is something of a Halo-clone, which is constantly compared to Halo 2. Remember, the main criticism (and admitted fault) behind the second Halo was how it was rushed and didn't have the few months of polishing time the original had. The developers have had all the time they'll even need on Halo3, and it looks like it's going to be the absolute pinnacle of its type of gaming, and I believe it's going to have one of the highest attach ratios in the history of video gaming, not counting bundled titles of course. Then again sales of over ten million are far in the future, due to the not all that high and slowly growing userbase of the 360.

Super Mario Galaxy on the other hand is the true successor of Super Mario 64, and hopefully brings back the awesomeness to the series after the slight drop in quality that is Super Mario Sunshine. Nintendo's best developers have had years and years to forge it into a masterpiece worthy of the greatest games of the 90s. It's probably going to beat the best selling Gamecube games on name alone, and has a solid chance of hitting octuple digits if it's as good as we hope, especially if the Wii ends up moving around PS2-level amounts of consoles.
