Quite a dichotomy exists when considering the question of “What is an acceptable review?” First of all there are the writers-attempting-to-make-a-living who simply don’t have 100 hours to play Baldur’s Gate II – Then there are the readers who deserve as complete a picture as possible about the game in question.
In an ideal world reviewers would load up a game, pretend they had paid $59.99 for it, totally ignore the fact that they’ve seen more gaming software in a month than a lot of people see in a decade–push that particular reality right out of their minds. Then, if the game is finite, they should play right through the final cutscene, or it’s like walking out in the middle of a movie, right?
Then, if multiplayer exists, they should try out several multiplayer modes. (If it’s multiplayer-only, then they luck out 'cuz it’s probably not finite.)
Then for RPGs with multiple classes/paths/etc., they should play the whole damn thing over again just in case another choice might make the whole product a lot better/worse than they had initially thought.
This would serve the readership. Then the publishing entity would hand over $5,000 and everyone’s happy, right? Oh. Right. We’re talking about $100.00.
In a lifetime of reading film reviews, only twice in memory did I see a critic admit that he walked out of the theater. They owe it to their readers to stick it out. Why don’t we? Because we can’t afford to… three-and-a-half hours of dreck, raisinets, and popcorn are one thing. Two weeks of scrambling-to-make-a-living are quite another.
So this necessitates that the game-review reader place a whole lot of trust in our first impressions. Are they entitled to more? Sure… probably… but they ain’t gonna get it.
There are reviewers I trust to do a good assessment without finishing the game, or to do a good assessment of a persistant or terminally episodic product based on a “reasonable” number of hours of play. And there are reviewers I wouldn’t, for the life of me, ever trust to convey an “educated opinion” after, say, 5 hours of play.
How long is long enough when it comes to giving the reader a fair shake? I’m not really sure. Depends upon the product/developer rep/cost/hours-it-would-have-taken-to-finish… I dunno. I think S2 should have left well enough alone… Anyone who didn’t trust Osbourne a whole lot would certainly look elsewhere. I know I would.
