I wanted to start a topic to see what happens.
Mine is Wazhack.
Its a 2d RPG dungeon crawler. The fun or the frustration is its random. The dungeon is randomly created. The potions are random. A red potion may be a healing potion the next time its a potion of blindness. Scrolls are also random as with spellbooks and wands. The gaming trick is get far enough and start reading scrolls. The scrolls you have the most of are usually Scroll of light, Scroll of Mapping or best of all Scroll of Identify. Once you know The scroll of Identify you can start Identify your scrolls and potions. Or end up reading a scroll of destroy Armour and be in a bad spot.
I have 241 hours as of this post beat it twice with 2 different character types. Still playing. Best guess 2 may be 3 hours to beat and you can save in the middle if you like.
Its not easy you have to use your brain!
