If you have never played a Heroes of Might and Magic game, shame on you. This series spans back to my early childhood. The Heroes game I played the most was WOG, a custom expansion for HoM&M3. I loved this series and logged countless hours into these games. They are indepth yet easy to pick up, hard most of the time unless you are a seasond vet.
Build up your town. Recruit Troops (this version allows upto 7th level units). Upgrade your buildings to get bounses, like resorces, spells, or your creature dwelling. In HoMM5 you can select from 2 differant upgrades for each creature type. You have a army that is lead by your hero(s). On the map you will be just one person, but if you attack a creature stack or another player the map closes in and you switch to battle. This is simalar to RPGs where u wander around a map and you trigger combat then cut screen, there is your party ready to kick some butt.
This game allows may differant types of combonations with town faction/hero selection/creature types/pre-gen maps/campain.
New Features include the single player campain where you play as the orcs, and i think the 'caravans' are new to this expainsion. Caravans can be selected where you hire creatures and there u selecet where you want your guys from and the caravans will farry you troops from creature dwellings or even other towns.
I must also point out this game does have some flaws. First I mention the AI, to be honest the AI in heroes games has never been the best and this game is no exception. Many people claim that the normal setting is "Comp doesn't even try" (Yes they will even not capture resorce nodes, and be crippled by larger maps). Also people claim the hard setting is "Comp Cheats way to much". Don't be upset, they are fan made mods that tweeks the AI so its more cunning and less cheating. The random map generator built into the game is poor compaired to previous games. Lack of teams is the biggest issuse, for multi player games. If your playing single player the random map gen is fine. NOTE: the time for the computer to move on random maps seems to take extreamly long time even with a 'newer' computer. YET AGAIN, fans of the Heroes games shine through as I have found 2 other random map gens, I've only used one and it worked great, but the comp lag remaind.
The best things I like about this game, caravans (YAY), the gfx (not the best but better then earlyer Heroes), the camera controals(feels natural, smooth when combined with arrow keys), balance (like most heroes games there is no horrid balance issuses), and the community (you will have to resort to the web for forums,)
Heroes games have a place in my heart and this one is no exception.
