OK, thanks to the suggestion
here, I've downloaded the demos to both of
Soldak's games - Kivi's Underworld and Depths of Peril.
And I'm sure I am the opposite of nearly every person here, but I liked Kivi's and didn't like Depths of Peril. (
Inside Mac Games, among others, felt the opposite...)
Kivi really is a 'hack & slash' - it's almost more of an arcade game than a true CRPG (it almost reminds me of a 'Legend of Zelda'-kind of console game). But it's pretty entertaining without being too challenging, and is a good game to play in, you know, 20, 30 or 60 minute installments (which is pretty much what the developer bills it as being good at - he's right!).
Kivi definitely lacks the depth of Eschalon (I do wish there were a few more skills and attributes you could develop as you go along - I'd rather have that than the zillions of kinds of 'power-ups' you come across), and it probably won't have nearly the replay value.
But I'm leaning in the direction of paying for the full game (I've got to do
something until Book II comes out!), so that has to say something.
Depths of Peril, OTOH, I've tried giving two or three chances to. But, rather than finding it "challenging", I'm simply finding it too complex and frustrating. I can see why harder-core RPG players would like it (it's almost more of a strategy game than a RPG!). And I actually sort of like the 'grid-map' way the 'world' is randomly assembled with every new game. But there's just too much going on in this one (I still have
no idea how skills and such work with the characters in this game!), and too little time to pull it all off. So, DoP I think I'll be giving a pass to.
Bottom line: Both games lack the elegance of the character creation and development process that Eschalon sports. But, Kivi, at least, is a relatively entertaining diversion.
