Why can't I create sequels to past games?

Game Dev Tycoon bug

I tried to create sequels for games I created in the 1st office but it won’t let me.

try another platform. :wink:

suppose you wrote the original game for G64 which is not available anymore,
just choose a contemporary platform, that should work. :wink:
