It's important. That same room experience people talk about is usually just a bullshit excuse for why they didn't put in online. Truth is that after grades k-12, it becomes more difficult for people to find three other adult humans (as in not man-babies) to sit down and play a video game like this with. Nintendo still believes it's the future world of 1999 and manages to stay on par with the Dreamcast. When/if they do decide to bring more things online, then they will start saying something about how it's a breakthrough that you can play Mario across the internet. I'm also not saying that local play is bad. Littlebigplanet has a similar play structure and supported both online and local; online was smooth most of the time but on the rare occasion when I could try local, it obviously was at its best. Options are nice, and in the year 2009, these things should be expected in games.
