Heroes of Might & Magic III: Horn of the Abyss

And I'm no longer waiting for 3.59. I've had enough of the bugs, errors, and half-baked features of 3.58
and as for the campaigns, why on earth couldn't they make them better:) I'm waiting for this addon:)

Regarding the ambush. I think it was mentioned in this thread that you can install it not only on SoD 3.2, but also on VoG, though it will be a bit more complicated there:)

Added after 4 minutes

By the way, if I'm not mistaken, there was a map in Heroes 3 where you walk with one gold dragon—it's an easy map, but a block of text appears on every turn. You had to press enter about 20 times per turn... Is it possible to make a map something like that, but just replace the text with Russian and change it as White Lizard suggested?

Well you, uh, don't get too greedy;) they have a lot of other very important work right now:)
and they shouldn't be distracted by maps that aren't part of the campaign scenario... when everything is ready, then maybe they'll get to the maps. (but that won't be anytime soon;) )
