Sorry for the following post, I was reading about some shield talk in the beginning of this thread, and I wanted to trumpet my favorite shield description from any video game: the shields from the Independence War series.
Basically, shields act like point defense, rather than magic bubbles. They are basically shield emitters on very fast gimbals that rotate to disperse damage from a limited number of directions. In IWar, a ship has two of these, protecting two sides of the ship, and they are overwhelmed by more than one shot at a time: then the hull absorbs damage. Otherwise, they easily disperse energy, and "recharge" extremely quickly. It's great protection when you're up against a limited number of opponents, and you're positioned well, but more than a few guys shooting at you will definitely result in hull damage.
To top it off, IWar shields don't protect engine emissions, and your backside is 100% vulnerable.
To quote GameSpot:
Shields aren't all-encompassing energy fields, as in other space sims. In Independence War your ship has two shield projectors, one protecting each of its upper and lower hemispheres, and each projector is only capable of shielding you from one attacking ship at a time. Using your weapons and shields effectively is difficult, but until you learn how to do so you won't have much of a chance against multiple opponents. Even once you're experienced, you'll have to choose your fights wisely. This is definitely not a game where you can be successful by charging in and trying to blast every enemy in sight. Time to retire your "Iceman" instincts.
I am NOT proposing that shields in TLF work in this way, rather, that there may be a more satisfying and interesting way to deal with shields and recharging than the way they are currently being used. I also think point defenses are inherently cool, and marrying the rather boring play mechanic of shields to them is pretty neat. Is there something we can crib for TLF?
