You’ve never owned your games. You owned the media they came on but legally you only ever had a license to use the software. Depending on the license agreement (the thing where most people click “I agree” without reading) you had more or fewer rights, such as transfer of license, but the way things work legally ownership of software seems to mean the more of the copyright ownership. Maybe like a book: you own your copy of the book but you don’t have the rights to print more books or make a movie based on the book.
