And why is this? It's a perfectly grammatical sentence. It's a chiefly British way of speaking, but that follows since the game was localized by a team including Rhianna Pratchett. Everybody trying to hold up the game as some sort of quasi-translated piece of Euro kitsch is barking up the wrong tree. This, like Risen 1 before it, is a quality British script and dub using professional actors.
I mean, Christ, that video. "I can't do anything," was a response from non-important NPCs when you tried to talk to them. Presumably it was written in response to a generic question your character would ask, like "Can you help me?" It's a brush off. Like saying, "Fuck off, don't talk to me." And the character was saying it over and over again because the player was rapidly hammering the A button to try to talk to the NPC. I guess anything will be "funny" if you exploit the fact that it's a computer program and play inappropriate music over the top of it, though.
The game isn't perfect by any means. There are plenty of legitimate targets in the game's make up. The combat isn't very good in the beginning, the time of day shadows (cast by the sun) don't move smoothly like they should, and most distracting, the object pop-in and level of detail shifting are both way too noticeable. But acting like the game is janky because you took a nearly dead character and had them jump off the top of a fort at the top of a hill and it resulted in the character dying? Jank would have been not taking any damage after all that.
I'm not saying you have to think the game is good, but show a little respect to the developers by not spreading ridiculous misinformation "for the lulz."
If anybody's still reading, I've put in about six hours now. I think the game is very definitely of the same quality of Risen and the earlier Gothic games. The combat is weak at the moment, but then, so is my character. There are a ton of talking and exploration quests with good rewards that they clearly intend you to build yourself up on, so start with those. Don't try to run into the jungle and fight jaguars wearing nothing but a pair of pants and a filthy shirt you found in the slave house.
I'm convinced the most negative reviews are from people who just don't get this kind of game.
