Gee, the save vs. no-save argument, I've never seen this before...wait, yes I have.
The only thing to consider is this:
-When games come out with save option, there is no outcry of "oh no, why is there a save option! The game is ruined!"
-When games come out with no save option, there is an outcry against it.
Just put the damn save option in and have done with it. Someone will make a trainer anyway.
