A new thing came to life after years of development, and it's great - rework of the old-school classic Heroes of Might and Magic II in Heroes of Might and Magic III's engine - Heroes of Might and Magic III: The Succession Wars Mod.
This is a first look at the just-released beta version, and it already plays pretty great and I enjoyed the hell out of it, the beautiful, characteristic graphics and sounds with music of Heroes II and advancements and just "hitting things right" of Heroes III engine are a match made in Heaven (or the Pit, up to you :d). Some bugs are present as expected, it is, again, a just-released beta after all, but the mod is already well playable and recommended for trying out - it's a blast :-)
Make sure you follow the installation steps properly, otherwise you might face issues - here is a step-by-step guide (it's really damn simple - don't forget you need a clean HoMaM3 install) - that's also a forum where you can report bugs you encounter to help with development.
