From the PlanetXbox360.com feature list:
"Kicking off a brand new feature here at PlanetXbox360.com we are listing the top 5 Xbox 360 releases for each month of the year, starting with June of 2010. The list will be in the order from 1-5 that our top editors would recommend them, if for example you only have the fund to purchase one game this month our advice would be to pick up whichever is in the number one spot, then going backwards to number five if the extra cash is available to purchase more than one Xbox 360 release each month. Some months only see seven or eight Xbox 360 releases but other months (like November) will see nearly twenty; either way we will only choose our top 5 for that month. Without further ado we present the top 5 Xbox 360 releases for the month of June 2010:"
