This was a no-brainer. More in depth story and character development than Diablo but without having to worry about tinkering with a party of five or six with varying abilities. The customization of the player-character in DD provided enough leeway to concentrate on some skills over others yet allow for crossover abilities if needed. The story was engaging and complex with a vast number of side missions if so desired. It's often the case that I feel obligated to do every side mission or cover every inch of every dungeon just to get extra points and loot. DD provided much opportunity for both. I also found the "loot" to be well thought out -- not giving the player anything that would make him invincible and ruin the gameplay.
One complaint and what made me give it a lesser rating were the annoying albeit few times when I just could not figure out how to meet up with such and such person or find a way to provide such and such item for some NPC. I felt that at those times, the clues provided to figure out the puzzle/quest were too sparse. Although I liked the non-linear nature of the game play -- allowing the players to mostly roam free and encounter things by themselves -- I felt there were a few too many frustrating moments of running into some enemy that was about 40 levels (exaggeration mode off) too difficult to fight. Although I can see where that would give the game a more "real world" feel to it than keeping things locked until a player can face it.
There were also a couple of technical glitches that needed to be balanced early on -- resolution and system crashes being some of them. I eventually got the crashes to a manageable level (usually only happens when a dozen enemies are all casting spells at the same time) and frequent saves spared me the grief.
All in all, a very enjoyable game and an eater of many hours filled with fun. At the price this game is offered on GOG, it is more than worth it. A steal, actually.
