I can recommend LIVAN - base game IVAN, Inter Vehemens Ad Necem or some such. Quite snazzy, but hard. Also, the tiles version actually represents data graphically that I don't think the game tells you otherwise - food will have tiny black pixels buzzing around them if they're spoiled, and your limbs (which have individual HP and can be destroyed/severed - bad news for limbs, fatal news for your head or body) will actually change color if you've turned them into different materials.
The body part system allows some cool random cruel deaths...
I love I.V.A.N. ..to bad it's development stoped at v0.50 ... but there's always LIVAN and other mods
Yeah, man. A couple days ago I was playing it, and I had no weapons or anything. A kobold found me, but I had low (8-9ish) arm and leg strength, so all my attacks weren't doing anything to it, I think.
Then suddenly, I punched one of it's limbs off. An arm, probably. It freaks, and runs away.
So I chase it, and now it's up against a wall. I try to kill it, but I'm still bouncing off it's hide or whatever.
Then I kick it. It falls, and bumps it's head against the wall.
Apparently this was hard enough to SNAP IT'S HEAD OFF.
That was pretty awesome. I believe I declared that character's fists to be MAGICAL SEVERING MACHINES, because I punched the limbs off other stuff with alarmingly high frequency as well.
Then there's the undersea tunnel's boss. This one time, the damn thing's minions chewed my arm off, so I freaked out and retreated off the level. Apparently this was a bad idea, because I had an acid rain wand, which is really effective against it. But now I have to fight through waves of minions to get back to use it, except minus an arm. I eventually killed it, by the way, only to die of a COMPLETELY avoidable bout of starvation later in the city - instead of opening a can and eating that, I decided I wanted to walk back into the store I'd just left to buy some grub.
My first try with LIVAN (as I played the vanilla IVAN before it) ended up with me being practically BLESSED by the random number god. Ommel hair armor on the first floor as well as numerous other sweet stuff, nothing particularly threatening challenging me...
Then I get to the boss as above, and I accidentally kill myself with bouncing lightning. I shot it diagonal, expecting it to bounce such that it WOULDN'T hit me, but apparently not.
I'd been using fireballs on the boss, too - hadn't run out yet, so I really had no reason to change to lightning. Goddamn. Utterly stupid death.
