Sorry if I seem rude, but my goal is not to speak ill of the company, just to defend a series I always liked, and I hope someone agrees with me. And sorry for bad english at times in my text as well.
Obsidian, in trying to make a game more extensive to also include players from the consoles in Dungeon Siege series, made a poor game and (worst) damaged PC gamers, launching the worst version of the game to this plataform. It is a great lack of respect with the fans of the series, mainly 'cause the game was born on the PC, and the entire base of fans of the series are on the PC, and it should be the main platform of the game.
It can be seen easily that all the simplifications that have occurred in the game are given by the fact that they decided to launch the game on the consoles - probably in an attempt to make more money.
There are games that are simply not possible to do on consoles. Strategy games for example, do not work well. RPG games like Dungeon Siege, where you have to control a certain amount of units, each with their inventory, items, settings, magic, etc, either. But why? Because consoles has no keyboard or mouse...
So what Obsidian decided to do? It's simple, we will reshape the game! Let's remove the possibility to form and control teams (the biggest crime) - and bye to the mule too - let's change the way the character and camera are controlled, we decrease the amount and complexity of the loot in the game, we completely remove the possibility of making a new character, even the name cannot be changed, let's do characters who have little variety of skills, in fact, we reformulate the whole scheme of skills to the powers become less complex to organize in the joysticks of the consoles, we will make it extremely linear and we still will do a history full of uninteresting characters. Blood and mana potions? Forget, too many buttons... You also dont evolve your habilities as you use wome weapon or magic (another big crime)...
Soundtrack? Where is the exciting theme song that plays at the beginning of Dungeon Siege 1 and 2? The game has no exciting song. Graphics? They are beautiful, but the scenarios are a bit generic...
So they basically changed all the series had, and made a completely different game, but they put the title Dungeon Siege 3, although the game is more closer to the game Lara Croft and the Guardian of Light that some game of the Dungeon Siege series. Except that Lara Croft is a great game and Dungeon Siege 3 is not. In fact, it seems that tried to do a Lara Croft more focused on RPG but in the end did not work.
So they made the game focused in the public of the consoles, with their limitations of controls, and then when the game was being converted to PC they made another mess. Rather than adapt the controls and facilitate the movement of the character, not ... movement was very bad. How could complicate something as simple as walking and control the camera in a hack-and-slash RPG? We have to rotate the camera all the time, moving the character with the mouse is bad and with the directional (WASD) is just terrible. And yet, instead of just having to click in a item on the ground for the character to go and pick it up, no, we have to walk to the item and press a button on the keyboard to get him to take the item, something extremely uncomfortable.
Dungeon Siege 3 is a total disappointment. I leave here my dissatisfaction with what the company did with the series. I hoped that Dungeon Siege 3 was a good competitor for Diablo 3, but it have no chance, unfortunately. You changed the game soo much that it cannot be called of Dungeon Siege. Please, if you will do another sequel, go back to the style of previous games - or give it back to Gas Powered Games. It can have innovation, but can not be a different game. And focus on the PC, 'cause this game should never have left for the consoles as the main plataform.
in short: You simply removed much of the game that formed his identity, just removed - without justification for PC gamers - , and changed the format of the fighting and added bad controls.
oh yeah, and where the game could be saved, which is the co-op multiplayer, get disappointed again because the characters are just temporary for that match.
