Well, as you mentioned, YMMV, but outside the blurry thing and the posible bug (if I ever get it, it'd be the android port, so no idea if those issues would also be there as in the iOS), that sounds like the best version for me.
I like the DS script, didn't found that tedious the Lost Sanctum or the Vortexes, don't mind the Arena isn't there, the controls/buttons thing is a non-issue (already played the first three DQ games on mobile, so I'm used to the controls by now), and I don't find it a big loss the bonus features. Like, things like the in-game encyclopedia? Not something I'd need to check in-game. Can just use the Compendium here. The anime cutscenes? Outside the Fall of Guardia one, it's nothing really new, they were in-game scenes animated scene by scene, as it were. I have Youtube if I really wanted tosee them.
So yeah, and being at 195 MXN (a little over 10 USD, at current exchange rates), it's not a bad bargain, I'd say.
