Chessbase 12 Free 2021 Download Torrent

I just recently realised that the chessbase software is available on Steam, which would seem normal to me if it wasn't almost half the price compared to the version on the official website. I have chessbase 16 and chessbase 17 is on offer but I don't want to pay for a cut-down version, do you know if there is a difference?
