I spent many many hours on this back in the day and my god, it has held up extraordinarily well.
The graphics are horrible and the UI isn't great and the bugs are plentiful and the balance is nonexistant and the AI is beyond retarded but holy shit what a great game. I'm just finishing a romp with all-Life spellbook Halflings, I think my next one will be all-Death or maybe the unpredictable and whacky zero-spellbook mage.
MoM redone on a tablet would absolutely rock. I don't know if you'd turn a profit, the gaming community has derpified to a degree unimaginable in 1995.
On the other hand there remain glimmers of light, wee islands of hardcore gaming. I've been dabbling in Dwarf Fortress. Detailed? Cumbersome? Twisted? Insane? Addictive? Yes.
My first efforts ended in starvation or even worse, running out of alcohol.
I lost my last fortress to a goblin invasion.
My current fort is in trouble because one of my citizens is a secret vampire. Morale is suffering because of the murders, and I'm don't even like the way the fort layout turned out, I'm considering restarting.
Anyway if you're curious about DF I'd read this, http://lparchive.org/Dwarf-Fortress-Boatmurdered/
