In Fallout, even if you have 12 AP (which is a lot), fast shot trait, bonus rate of fire perk and the fastest Magnum revolver, it is just 6 shots per round. And they are not that powerful. And after that, you have to reload it, so it will be only 5 shots per round. Or 3 aimed shots, which can be much more powerful, but you have to work for it!
In Arcanum, boosting DX to 20 leads to 25 AP already, which means about 9 strikes with an average sword, and if you have put at least 3 points in backstab and at least 1 point in prowling, most enemies die from one strike from behind. Now put 3 points in temporal, and you have speed of 50, which means you can instakill about 17 enemies in a round. Of course, this is melee, so you have to move too, but movement is about twice faster than in Fallout. And I am not talking about Tempus Fugit here... This all ultimately leads to the fighting style when all enemies die before the fight really starts, which is boring, stupid and you don't have to worry about armour at all. Of course, you can forget about backstab or even go with guns, but that feels like playing Fallout with bare fists, which is fun, but in a twisted way.
