Locked on aiming is a sin to gaming.
I couldn't disagree more on this. I really hate constantly seeing people thinking that lock-on aiming is some kind of assisted mode. It depends on the game, sure, and if something was really made for aiming, then yes, lock-on could not have its place there, but it's not a reason to completely despise lock-on systems either, if the game was designed around it, it can be really good.
I personally really don't have any fun in most shooter, especially 3rd persons where it's just a cover shooter, hiding and shooting, it's incredibly boring to me, I don' thave fun with the action of "aiming" in such games. However, when games are designed with lock-on system in mind, it can be a very different style of gameplay, with the action being focused on your movement, your character actions, instead of the aiming.
In the ps2 era there used to be a lot of games like this, and I preferred it, for example Star Wars Bounty Hunter was pretty great at that, it had a lock-on system, but the game was designed around this, you were not supposed to play without a lock-on, so the difficulty was adapted to that, you had a lot of ennemies, you had to fly around, do backlips while switching quickly between different ennemies etc, it was super fun and not particularly easy at all. It make games feel more like action / combat games, rather than just gun shoot / aiming games.
So really, no, locked on is not a sin, if the game was designed around it, it's a different style of gameplay, and I really can't see why people comletely reject his idea. Also free aiming makes even less sense on a controller, it's just so dull and boring imo.
