These were the top 20 Xbox Live games of 2010. I've played none of them. Someone asked me a few weeks ago why my last log in time on Xbox Live was a million years ago. This is why. Nothing is wrong with the system or the games, but none of the top offerings for the system really speak to my gaming preferences. I like the nerdy sh*t. These games are too cool for me.
Major Nelson also has the top 20 arcade and indie titles on his blog. Check it out.
