Dragonshard implants the best of the RPG and RTS into one game which is something new and fresh but it doesent develop..
Dragonshard story is about 3 races that fight over the dominance. The Lizards, humans and the underground "monsters" will all fight to secure their dominance in the dragonshard world. Although the story is pretty good, it doesent take you deep with in it, and it's rather only a base story than a deep interesting story.
From the begining you'll be abble to choose from two campaigns. Then on the first mission you can choose your hero, there are four to choose from but it's not a single character developing as in the second mission you can choose any other of the four heroes, which could be good if you know the herose better and challenging at times as you'll need to force only one hero to develop it so it can fight the tougher monsters you'll face in the game. The heroes are not too interesting or special to play with as they are only with average strenght and power so its better to send 3 solders you can build at your base than sending the hero alone as it will surley die.
The graphic engine isnt't impresive as there are many games from the RPG and RTS genre with much more better graphics. You can zoom pretty close to the ground and see the heroes or monsters from up close but by doing that you wont have an overview of the map and you wouldn be abble to see any enemies that are on your path. The default camera is better but it makes the characters on the ground too small.
The gameplay is average, although with this kind of game more could have been done the improve the gameplay. The maps are "easy worked" as thay lack details and objects that would enrich the enviorment.
Overall the game is good but will get you bored pretty soon and at least for me the most important in a game is to be interesting and fun to play.
I'd advise you not to buy this game as there are much more better games available now or you could stick with the well known warcraft 3 and play dota on battlenet or any other map available for the game as will offer you more fun than this new game-Dragonshard
