Pretty much. It’s essentially a dynamic Diablo (original) in that you always have a town that serves as the focal point, and a dungeon underneath with various amounts of levels to it. There is no main storyline, you’re just given quests that involve the dungeon, and occasionally stuff happens in town like the town is attacked or it’s people revolt, and you have to address that. Once you reach a certain point, the town is “saved” and you move on to the next one, with a new random dungeon and events. It sounds like it would get tedious quickly, but it really doesn’t. Something about it just keeps you plugging away…one more quest, one more item, one more town…
If your group is into ARPGs and doesn’t mind that there isn’t actually a plot that can be “finished”, then yes. The myriad of class/skill combinations means everyone can play a character that does something they like while still working well together. Keep in mind, the game is eight years old, and was an indie title to begin with, so graphics/sound/etc. are obviously a bit dated.
I also highly recommend the Demon War DLC as it adds more class combinations and lots of content…however it’s not on sale at the moment, and there is no need to own it to enjoy Din’s Curse, so maybe wait to see if you like the base game, then grab Demon War next time it’s on sale.
