How about adding methods for handle files?
Like CreateFile, DeleteFile, CopyFile, PutLineInFile, DeleteLineFromFile, e.t.c.....
I'm thinking about Grim Fandango where everytime you saved a game it genarated an html file which contained all the dialogues you had in the current game.
(I'm not goint to use that for my first small adventure but I think it could be usefull for some other people or me in the future.)
