I am running lots of 68k applications and games on AROS, I mix native AROS and 68k libraries, have added original AREXX and installer and so on and this is both running on emulation and native on classic hardware without PPC addon. Try that with AmigaOS or MorphOS :-). I use AROS 68k of course. So for every purpose you can choose the right version. Of course it is not possible to mix f.e. X86 and 68k but the price of it to stick with old hardware is way too much in my view.
