The shield system from the X-Wing series is beautifully designed, with the ability to choose whether your shields are front-facing, rear-facing or all around, and can change on the fly - so you can go fully defensive at the front when making an attack run on a capital ship, then pump all the power to the shields at the rear when the run has finished and you are pulling away...
...while at the same time managing power levels between shields, lasers and engines which determines the rate at which they recharge - or even deplete if you *really* need engines right now and not shields
...and then Tie Fighter adds an extra layer to the design of the shield system by, well,
taking them away - at least in your first few vehicles, where you're entirely dependent on the sheer speed you have to survive - which does feel like a significant step-up when you do graduate to the newer units which *do* have shields available.
It's one of the most interesting and nuanced approaches to shields in vehicular combat that I've seen, and I love it.
