As someone who's currently interested in Atari 2600 development, I can tell you that MobyGames is way off in their count, even if you limit the count to physically-released games. There were well more than 10 new physical releases in 2025 alone.
It helps that developers do licensing deals with a few companies that produce physical cartridges with boxes and manuals on demand, but there are also still a surprising number of people making physical copies of games for sale in advance.
