Alongside the standard edition, a digital deluxe edition and a collector's edition were made available for purchase. The collector's edition featured a different packaging, an artbook, bonus in-game content, a behind-the-scenes DVD, and one issue from the "" comic series. Although "Mass Effect 2" was released at the end of the month, it became the second best-selling game of January 2010 with 572,100 units sold, behind Nintendo's "New Super Mario Bros. Wii". Shortly after "Mass Effect 2" was released, the game's font size and coloring was criticized for being too difficult to read on some standard-definition televisions. Because BioWare considered it a design choice, the company could not resolve it, but stated that they would take it into consideration for future games. In February 2020, BioWare released a patch that addressed minor issues such as crashes and long load times on single-core computers. A second patch, which reduced the amount of mining time required to acquire upgrades and fixed other minor issues, was released in June 2010. At Gamescom 2010, BioWare announced that a PlayStation 3 version of the game was in development. Microsoft responded to the announcement that, despite losing the game's exclusivity, the Xbox 360 was still the most appropriate console to play the game due to the game's compatibility with the original "Mass Effect", which was only available for Microsoft Windows and Xbox 360 at the time. The PlayStation 3 version was released on January 18, 2011, in North America and January 21, 2011, in Europe. After some PlayStation 3 players reported that their save files can become corrupted if the game crashes unexpectedly, BioWare released a patch designed to combat save bugs and crashes experienced. The PlayStation Network version accounted for more than 10% of the game's overall sales on PlayStation 3. As of April 2011, it was reported that both the original "Mass Effect" and "Mass Effect 2" combined had sold more than seven million units worldwide. In 2012, a compilation featuring the three main games of the series, titled "Mass Effect Trilogy", was released for Microsoft Windows, Xbox 360, and PlayStation 3. In 2016, "Mass Effect 2" was added to the list of backward compatible Xbox 360 games on Xbox One. New purchases of the game are provided with a one-time use card granting access code that unlocks the game's Cerberus Network, an online downloadable content and news service that enables bonus content for the game. However, users who bought the game used would have to pay for the Cerberus Network separately if they wanted access to the new content.
