Do a search online for 'Dungeon Siege Mods'. Personally, I found the game almost unplayable, until I downloaded some mods for it. I got the 'unlimited summons' mod which allowed my mage to play solo (I PASSIONATELY HATE having to control a party). With this mod my mage could summon as many creatures as she liked (a bit like DD's scorpions) and they won't vanish after a few minutes, but will stick around till they're killed.
There are a heap of mods out there, try a few of them out, they certainly improved gameplay for me. But Dungeon Siege will never be as good as <img src="/ubbthreads/images/graemlins/div.gif" alt="" /> no matter how many mods they make for it.
