Reviewing add-on packs is always problematic. This one's thrown up special ones all of its own.
Heroes and Might of Magic V is the (PC) chart-topping turn-based exploration/strategy game. As in its prequels, it alternates between exploring a map and collecting various magical gubbins and playing out the skirmishes in a chess-like fashion (with masses of character advancement and army recruiting inbetween). Liking the genre and encouraged by my dear friend Egon Superb's 8/10 review, I was looking for an excuse to play it, so offered to "do" the add-on pack. This clearly involved playing the original to get a sense of the game before moving onto this new collection of Mightiness and (er) Magiciness.
We hit the problem. I don't like the original very much.
