It isn't might "or" magic, so you don't have to choose which games to get in this latest Humble Bundle, which contains a megaton of Might & Magic titles in the series.
The bundle includes everything from Heroes of Might & Magic II to the latest title in the series, Heroes of Might & Magic VI Gold (which includes all the expansion packs to that title), as well as the Might & Magic 1-6 collection, the newly released Might & Magic X, Clash of Heroes, and the Dark Messiah of Might & Magic game from Arkane. There's even Heroes Online, which is pretty sweet.
Head on over to Humble Bundle if you're interested in one of the best bundles they've come up with yet. Keep in mind that you'll need to pay above the average price to get the majority of titles, and $15 to pick up Heroes III HD Edition and Might & Magic X Legacy.
Most of the games are downloadable via Ubisoft's uPlay store, though some are offered through GOG and Steam.
Your purchase will support American Red Cross, Charity: Water, and Doctors Without Borders.
