Pythro: I see it is on sale is it worth the buy? Are there any game breaking bugs? And like the title is it good?
It is a good game, however it can be a little hard to get into at first. Raze pointed you to some starter tips that I'd suggest you read.
Initially it will appear to be yet another Diablo clone, and it certainly has similarities. However you'll soon see the differences as well. Firstly, there are no respawns, so not only does that mean that you will end up with some very empty areas, it also means that there is a finite amount of XP available to you for levelling, so you have to be more stategic with who you kill.
I seem to remember that when I played the original disk version, I played as a mage, and charged down the orc encampment with a freeze spell and a load of mana potions. This mean't that because they were so much higher level than me, I quickly levelled up way past all the other creatures around, and then had little fun just destroying eveything else on the map (until I reached areas where the level got back into sync).
Another main way it differs from Diablo is that this has a proper story, and is a good lead into Divinity 2 (later rebranded to "The Dragon Knight Saga"). Which is well worth playing.
So, yes it's a good game, if you like Diablo style games. However it's not quite like Diablo.
