I want to like this game. That's probably why I've got so many hours played, despite any session never being longer than 30 mintues or so. The game is dull and frustrating.
Din's Curse presents itself as a dynamic, living world that continues to evolve as you do your own thing, regardless of how you play. This sounds fun until you realize that quests can become unfinishable as you're attempting to complete them through no fault of your own. Necessary NPCs in town can be killed while you're in the dungeons below. Monster spawns change as the game progresses (randomly), meaning there aren't always enough monsters to actually complete your objectives. One solution is to just wait and see if something changes after a while, but you don't get many quest slots.
The graphics are bad. Really, really bad. That might not be a deal breaker for most people, but it's definitely a mark against it. The music is mediocre, and voice acting is almost completely absent. Dialogue menus and the inventory system are even worse.
Combat is a mixed bag. The class system allows you to customize your playstyle to a significant degree, but with so many options you start to realize that there's a lot of overlap. Still, the class system is probably the best reason to pick up this game. It's got a healthy amount of choices and encourages replay. Combat itself isn't so great though. Animations are awkward, weapons lack impact, and many spells trigger cave-ins that can help or hinder. (usually just hinder)
Dungeons are a bore, and that's all you get. There are very few changes to the scenery as you explore one dungeon after another, deep below the next randomly selected doomed village. They're randomly generated and all end up looking exactly the same.
All in all I really can't recommend the game to anyone. The game feels like something that would have been released in 2002, not 2010, but it doesn't even have that bubbly nostalgia feeling. It mostly just makes me sigh and appreciate how far good games have come.
