I have dealt with it plenty of times on other topics. it's a bad argument. Some people want the game to be more realistic and some people don't, and yeah if i don't look before i leap i don't want to be able to bail out at the sight of trouble. you control your character, but you just have to be careful.
"changing direction in the air IS gameplay"? wouldnt not being able to change direction also be gameplay? i don't really understand what you meant there. same goes for whatever you say is "playing the game"
No, it's a valid argument, it is a realm where a guy with an amulet can summon the avatar of a god, the avatar just happening to be a large dragon made of fire that can breath steam and turns to stone afterward... something like "I shift direction in the air", really is nothing compared to that, also remember that there were levitation spells in past games as well.... levitation would be pretty bad if you could only move forward....
Not being able to change direction isn't gameplay no, for the same reason Final Fantasy XIII is not really a game, all you can really do at that point is watch, that's more like a film then a game. Games are interactive, it's not interactive if you are stuck in direction. Also aerial shifts have been common in computer games since the early days of platformers. I really don't see what you have against it, in a game like fallout 3 what is actually trying to be some what realistic I can understand it, in a fantasy game set in a magical world... realism really is the last concern, enjoyment of the game and being able to do those things you CAN NOT do in real life is why you'd get a fantasy game to begin with... what's the point of a fantasy, if you are going to bind yourself by the rules of the actual physical world? That's pointless. It is a fantasy setting for a reason after all, all worrying about realism does is destories that.
