Complete control of additional characters is also very satisfying because it allows you to fully sculpt multiple players simultaneously - or simply click on the recommended upgrades instead. With a number of very finicky requirements for some of the more esoteric "Prestige Classes", it would be impossible to see very many if only your main character was controllable. So, in addition to giving you complete tactical flexibility in battle, having a full-blown party scratches many itches at the same time on the role-playing side.
Putting you in complete control of the camera is also an improvement that puts this sequel leaps and bounds ahead of the original. In addition to the traditional isometric top-down view, you'll be able to sweep into an over-the-shoulder view with a flick of the mouse wheel, and rotate the camera around in any direction you choose. While the somewhat tricky and (at times slow) camera takes a little getting used to, it sets you inside a much more immersive environment, showing off the magnificent visual changes that are on offer with the sequel. NWN2 boasts full day/night cycles and a robust light engine which deftly creates shadows that actually effect gameplay - especially for sneaky types.
