All castles in Heroes 3.

That's true, I don't have a favorite castle, I can play with any, but I play with Inferno the least. I don't know why, but it doesn't appeal to me, although I'm not saying it's bad. And in general, when playing on random maps, the main hero usually has a maximum of half of the units from their home castle by the end of the game, the rest are either angels/wyverns or high-level units from other castles they've built. So, it turns out to be a kind of international team. By the way, a mixed army is the most effective, as it takes the best units based on a combination of factors and takes into account the enemy's army when making the selection. I'm saying this because many people get fixated on the starting castle and don't build other castles, which is a big mistake.
