Heroes 6 - Discussion

But mods can be made for the sixth installment, right?

Yes, of course. Someone has already made one on Hugo.

A dream would be a mod that turns the turn-based strategy into an RTS – a real-time strategy, like Warcraft 3.

That's really a dream :) It would require a complete overhaul of the source code. Although, in this case, it would be easier to make a new game ;)
