Heroes 5.5 WarGame Edition - Tactical Edition.

I would say something like:
- "however, Heroes 5 originally envisioned gameplay on different types of maps"
and here's what I remembered - in the original, both races and skills often have different advantages depending on the game's duration (for example, playing as Haven, you absolutely cannot prolong the game, and the opposite is true for Necropolis; you can also consider Dark Magic and Chaos - on a large map, it's better to choose Dark Magic, while in a fast-paced game, Chaos can play a good role, and so on). In general, I think this is a very debatable issue - you need to try it out - sometimes logic turns out to be useless, as you never know what will actually appeal to you, and let it be the most illogical thing :)
