If you intend to get HoMM V, either get he Gold Edition which has all the goods, or then just Tribes of the East, as it's a standalone expansion that has most of the problems of the base HoMM V ironed out. Biggest problem is that the base campaigns aren't in that expansion.

I liked the campaign storylines, but playing on Heroic, got stuck on the Warlcok campaign's third scenario, which is utterly ridiculous and requires cheats to get anywhere on the Heroic difficulty.

HoMM V is thematically much closer to HoMM3 than to HoMM4, which was too much of a crossover into AoW mechanics. Pity they did not keep the old HoMM3 world.
