Variety in character generation.
There is, of course, an idea for the regular game as well, but here the number of available units at the start, their combination, etc., already has an impact.
The combat is, well... I mean the large-scale battles, when there are more than 20 enemies and the calculations take several days). In this regard, I liked the old games, where there were small skirmishes, whether it was the expansion about the hydra or about the adventures of Halmaldir. There was a good balance in the social aspect/battles, just like in the second King's Bounty. And when the whole game is mostly dialogue, and at the end there is a massive battle... it's like the first King's Bounty, but in reverse).
