Whereas both TEW2004 and TEW2005 were written from scratch, TEW 2007 was being built on top of TEW 2005's source code. There were many new features, such as the ability to customise merchandise and a large amount of new contract types (short-term, etc.). A new installment of the series, "Total Extreme Wrestling 2008" (TEW 2008), was announced on the Grey Dog Software website on January 1, 2008. The game is largely based on TEW 2007, but Ryland made more than 100 changes and additions. The game allows players to import and convert their TEW 2007 databases. The game was released on June 7, 2008. The demo for the game was released on June 1, 2008. In late 2009, it was announced that "Total Extreme Wrestling 2010" (TEW 2010) would be released in early 2010. Some of the new features announced included a revamp of backstage morale, and several changes to improve the interface and to reduce the amount of time it takes to navigate through the game and to book a show. On January 20, 2010, Adam Ryland released the demo to Total Extreme Wrestling 2010. The official release happened on January 25, 2010. At the end of July, it was announced that "Total Extreme Wrestling 2013" (TEW 2013) would be released in December 2012. Some of the new features announced included an Autobooker, Fog Of War, Tribute Shows, Shoot Interviews, Legacies, and several other changes to help either make the game more realistic, and opened up more options in the database  Total Extreme Wrestling 2013 was released on December 16, 2012, with the demo version available on December 9. On January 8, 2016, it was announced that "Total Extreme Wrestling 2016" (TEW 2016) was in development. The developer's journal announced that the game would feature elements that would add more realism and would also include things such as backstage cliques. On April 1, 2016, the last day of developer's journal updates, TEW 2016 was announced to have a demo release date of April 25, with a full release on May 2. While in previous versions of the demo, the player could only play through January of the game's titular year, it was announced that TEW 2016's demo would allow players to play through both January and February of any year. On December 8, 2018, it was announced that "Total Extreme Wrestling 2020" (TEW 2020) is in development with an estimate release of April 2020. The announcement stated that Ryland had completely rewritten the code before reinserting older features to make the game "effectively a much sharper, quicker, more intuitive, better quality piece of work" and promised that TEW 2020 would be "the biggest jump forward in terms of quality the series has ever seen".
