If your only consideration when purchasing a game is fancy graphics, then NWN 2 will have you in paroxysms of delight. On the other hand, if you'd prefer your game to run well, be relatively free of bugs and feature an intuitive user interface to complement the riveting gameplay, then NWN 2 is a game that will see you hurling abuse at your monitor.
Camera control is awkward, intrusive and generally horrible. Even on relatively modest settings, the game runs like a blind, lobotomised paraplegic. The storyline is dull, the NPCs predictable caricatures (a Scottish dwarf, a sanctimonious paladin, a mischievous rogue, etc), and prior to playing the game you're required to download approximately* 396 terabytes of patches, hotfixes and updates. If you're still on dial-up, you'll be sucking mashed banana and milk through a straw in a retirement village before this herculean download finishes.
And then we have Obsidian's Electron Toolset, successor to Bioware's Aurora Toolset. Aurora was intuitive, relatively simple to use and allowed you to knock up a vaguely playable module in a few hours. By contrast, Electron is about as user friendly as a rabid wolverine. While interior areas remain tile-based, exterior areas are sculpted from a flat plain with a selection of brushes. As a result, creating any sort of presentable exterior area is an incredibly time-consuming process, involving a lot of “painting”. If you're crap at painting, you'll be crap at creating exterior areas in the Electron Toolset – unless you're prepared to dedicate enormous chunks of free time to practicing.
Most people have jobs and lives, and spending their weekends wrestling with Electron is going to seem little more than a masochistic exercise in futility. Shame really.
