Currently playing the game on Epic and enjoying it. I'm just done with the fight against the king of the Chaos Dwarves (and his golems and soldiers) ; though I did manage to win on my first attempt, it ended up being a close thing, mostly because the king hits like a truck.
I was a bit worried that the game might turn out to be a half-assed cash grab (name recognition sells and the Naheulbeuk audio series is fairly well-known in France). But the combat is really enjoyable, interesting and challenging. Once I've finished the game on Epic, I intend to retry it on Nightmare difficulty and I suspect it will live up to its name.
The humor and the general atmosphere are not exceptional, but I think that they're fine (some of the jokes are references to the audio series and probably don't work well for players not familiar with it). The exploration is unfortunately very limited and the game is really linear.
Man, I keep dying on the Wheel of Misfortune fight on Epic difficulty, and I'm usually good with turn based games... Am I missing something??? On to my 4th retry...
The Wheel of Misfortune is one of the few fights that took me three tries before I managed to win ; I don't really want to imagine what it's like on Nightmare difficulty !
On my last try, I gathered most of the party on the right flank (the side of the goblins) and left only two characters to tank in the middle (the dwarf and the paladin, I believe). That way, it takes a while for the orcs to reach you (the less time you waste fighting them, the better) and you can quickly get rid of the goblins.
The fight ends as soon as you've killed the goblin boss and his assistant. I think it's better to get rid of the assistant first (especially since her charm ability can be really annoying). She'll charge straight at your characters, so you don't have to chase after her. She has a lot of HP, but her saves aren't that great and she's quite vulnerable to stunning attacks and things like that.
The goblin boss has very high Evasion and very good saves, so I wouldn't bother with him until you can attack him with at least three characters. Ideally, he should be trapped in a corner to make it completely impossible for him to run away (you can't rely too much on attacks of opportunity, because one of the effects of the Wheel disables them for your party).
Difficulty settings are a relatively new feature in cRPGs
Not that recent. They existed in Gold Box games, though they were very basic back then (they only changed how many HPs your enemies had, and you would get more XP on higher difficulty levels, which went against the very concept of making the game more difficult).
