Wii/DS developers, pay attention.
The Sky Crawlers: Innocent Aces gives players choices when it comes to controls, and it is a much better game as a result. It doesn't force a particular control scheme on its players (like the DS
Legend of Zelda games). By allowing the use of a Classic Controller or GameCube Controller and not stubbornly clinging to gimmicky motion controls,
The Sky Crawlers makes itself accessible to players of all types. I prefer using the WaveBird by a huge margin, but the motion controls work well enough. Like I said, at least they give you a choice.
Sorry, I'll get off the soapbox and get right to the mechanics. Provided you're playing with the standard Wii-mote/Nunchuk setup, the two controllers act as throttle and flight stick. If you play through the tutorials, it becomes evident that the developers intend for players to play like left-handed gamers. Holding both controllers parallel to the ground maintains a steady cruising speed and attitude. Pulling the Wii-mote perpendicular to the ground will max out the throttle, while tilting the Nunchuk allows you to pitch and yaw. If you turn the control settings to Expert, you can roll your plane. Regardless of how you play, pulling off complex maneuvers on your own is almost impossible.
Luckily, the developers compensated for some of the inaccuracies of Wii motion controls. Maneuver Commands are preset actions that allow you to move your aircraft in ways that the motion controls couldn't possibly handle. Manual Maneuver Commands allow you to evade enemy fire by executing one of several scripted techniques. Tactical Maneuver Commands are a bit different. As you approach an enemy, it's wise to keep your eyes glued to the radar. A circle surrounding your prey indicates the maximum range you must maintain if you want to execute a TMC. Staying in the circle's diameter will fill the bar. The bar has three levels; the fuller the bar is, the better the result of the TMC. When you press the TMC button, you will pull off a ridiculous maneuver that will land you exactly at your target's six. There are a couple of problems with this system. First off, when you execute a level 3 TMC, your enemies will almost never even try to avoid your gunfire. Secondly, TMCs make some animations look extremely unnatural. However, TMCs give The Sky Crawlers more of an arcade feel, and I think that's worth it.
If you don't have an Xbox 360 (Ace Combat 6) or a PlayStation 3 (Warhawk) and are yearning for a reason to take to the skies, The Sky Crawlers: Innocent Aces is your best bet.
