Not true.
His update schedule has not gotten much longer, but his content has dwindled with each release..
He went from releasing a playable day per update, to 1/3 of a day per update, to 1 event per update.
The estimated completion went from 2020, to 2036, to 2058. Even L&P had to admit that it will take him more than a decade, now.
..and as people have pointed out, technology will advance and he will need to continuously UPGRADE his game. In 2017, animations were sparse, now they are widespread... which takes more time.
