CD Projekt RED is still working on its insanity mode, so it couldn't reveal much, but did say it's toying with plenty of ideas, like having dying delete your saves. Nothing has been decided yet, but it wants to make it super punishing without eliminating the fun.
You know, I tried playing Skyrim hardcore and was enjoying the death is a lot more undesirable. Except I realized after the second or third time I died that well, starting the game over and over again gets boring and it just makes me not want to play.
Some one suggested a better thing is if I die I lose all my possessions. It still is pretty punishing without getting boring cause I keep restarting.
(Yeah, I know, you say just don't die. But I'm not great at gaming but I do like the idea of a play through where death doesn't just mean you reload the last save and makes you a lot more cautious cause you really don't want to die).
My prediction for this game is that it will have combat that's not amazing, but still much better than that in Skyrim, and that it will catch a lot of shit for it.
I'll admit I like Skyrim's combat better than Witcher 2 anyways. If nothing else both are button mashers and I hate the have to target something mechanic before you attack. I'd rather have to aim myself and then attack. I'm kinda dismayed seeing there is a button for targetting in witcher 3. Hopefully it is just an optional way to play and you don't have to use it to attack.
Now Dragon's Dogma.. that had good combat (too bad it had sucky story. But the combat was so good it was just fun for that).
