I do not even get the transitioning part within this context. If you are pretty sure that the software you are using will not work on Catalina, then what significance does transitioning have? Having more time saying your goodbyes to your old games (in this case), or what? 32-bit applications will not magically turn into 64-bit ones.

In any case, I think it was a silly decision to "force" the customer to pick between old vs new software, but I am sure they can afford it. People will probably forgive them for it, and then completely forget about it. New users in the future probably will not even have anything to forget (or forgive), unless they want to run "really old" software, in which case people will just boo on them, and say "times change, technologies change, you gotta adapt, man" and the like which seems to be the case today with respective to both old software and hardware.
