Shooting from first person using a crosshair instead of a scope or iron sights is a kind of a concession to begin with; I do know most FPS games only use crosshair, or crosshair and scope, and it's the minority that have iron sights. However, that's how a gun is supposed to be fired. You're supposed to feel like you're behind the gun when bullets fly.
Shooting manually from third person is just ridiculous to me. If it was point and click, and you'd order your character to fire his weapon, then sure, but if it's you moving the crosshair, I just can't get over the disconnect. Then again, when I'm playing third person, I don't feel like it's me who's in the game anyway. It feels like I'm watching some random dude or dudette move around while I'm hovering behind the character.
I don't know if it's my countless hours spent looking through the first person view, or what.
In an adventure game, an RPG game, like ME for example, it's fine. It's point and click. I point to an enemy and Shepard rips it to pieces. I can understand that. I'm not Shepard. If it's me behind the gun though, my self-made character I mean, I want to be the one shooting.
As such, if it's going to be strictly third person, then I hope they do away with any real life skill -based aiming altogether, and make it a fully point and click system, as well as give us a ready-made protagonist whose story we are following, and not our own. Then I can understand watching the events unfold from behind the shoulder or above the head of the guy or girl.
I wish I could just abandon the awesomeness that is the first person view, but I've played way too many awesome FPS' to do that. Thus I can't but hope it's both views. Clearly I'm not alone though, since over 47% of the people who answered would like to see the first person view implemented either as the only option, or as a choice. That's almost half, and I know at least a few answered third person before the "both"-option was added.
Almost half sounds to me like we need both options.
