The difference of offline play in Heroes II and Heroes III.

...

Thank you. We'll look into the units a bit later – we need to gather some information.

Yeah, if people dig through the depths of their memory (judging by the activity shown – some are quite willing), I think the alphabet won't be enough.

At the same time, another difference came to mind.
In the second game, if you attack a blinded enemy unit, it won't get a turn in that round;
In the third game, in the same situation, it will take its turn.
