Lo-Fi Games

I was thinking of ways to make the game harder, how about having an option at the start of a game that can't be turned off, where you can't sneak, loot enemies, except animals, or steal from shops? could be called honorable mode

Hmmm... just like the Wanderer start or something. Sounds great.

Also an Ironman mode with no Load options and an ultrahardcore mode with all the NPC party number set to maximum (the requirements of the PC to move such a thing nowadays have to be monstruous, though).

I find hard to balance the hardware requirements of the last one, but the others seems easy to implement.

Setting maximum party members should actualy affect all parties. Big numbers should happen from time to time but lower numbers also should be present.
