Heroes 3 Complete with Unofficial HD Mod (https://sites.google.com/site/heroes3hd/) looks, surprisingly better on large screens, because how the resolution changes with the mod, it looks crisp and clear with the mod. But this HD Edition looks like they smoothed everything with 16x AA.

The Unofficial HD Mod fixes many gameplay problems with the original game, including the mouse lag, which is not fixed on this Steam HD Edition.

This is the most barebone Heroes 3 experience you get, with a new paintjob. I can't recommend this.
Multiplayer doesn't work, the mouse lag, no random map generator. Really just get the Complete version from gog.com. Cheaper, more content and with Unofficial HD Mod much better than this disrespectful release.
