I also watched his videos about IWD1+2.
This is probably also the reason why I never finished IWD and I will never start IWD2.
You fight one wave of enemies after the other and reload quite often but at some point I forgot why I was in this dungeon.
If you find yourself with nothing to play I would still encourage you to give IWD2 a go. I was surprised how enjoyable it was - there is more RPGness in there then I expected with high reactivity to out party class and skills (though as it uses traditional Inifinity conversation system, entering the conversation with right companion can be tedious at times). I found there were just enough variation in mission objectives and occasional puzzly intermissions to shake things up. I also found difficulty to be at enjoyable level, encouraging tactical thinking, rather then testing encyclopedic knowledge of D&D like Pathfinders.
