...I still don't even know what kind of game world it is - maybe there are dinosaurs there? :) :) :)
Not Krosh, it's simpler there, heroes on horses (this is already in the 5th game, on lizards and other dinosaurs, mammoths, etc.), and all the creatures are like in the others, only much smaller, and the upgrade is only for creatures of level 4, so you need to keep in mind that this is the graphics of 1996 and for 1996 it is very good.
Although in terms of the interest of the plots, the intricacy, it is in no way inferior to the 2nd, 3rd, and 5th games (I don't play the 4th, so I can't say anything). And in general, of course, try it, maybe it will captivate you so much that you won't be able to tear yourself away from it.:) :) :)
