This game was build in times of 32bit world and it shows. Sample: you go back to town via portal and when you return stuff appears new - shrines, enemies, drops - all of which you die not even know existed. Stuttering and other problems point to the same history and make this game resistent to repairs. Improvements into such an old game requires deep knowledge, but the devs of this game moved on or retired - not much chance to get needed patches or improvements. The ancient lore history makes it easy to connect to the game lore. The amount of masteries available (including the additional DLCs, which improved and upgraded the system - and are required if you don't stuck to this game) give you more than 50 classes to play (most dual masteries, but each mastery can be played as single as well). Some of this classes are easy, others not. But you can find the style that fits your way to play. My summary: rusty, not perfect, but still worth playing. I still do AND love it!
I own the standard edition and I formerly owned the CD version. Sadly this game does not work. I tried it, I checked the forums - nope no chance. When starting this comment I was asked to keep it to a player's view. I tried, but there is no playable version. I love and loved this game. But I just was disappointed with this version. GOG can do better than this.
