Just as with films I'll take something that divides opinion over a bland (but perfectly tailored MOR) experience anyday.
While I like them games like Halo 3 are really starting to resemble summer hollywood films - well made, expertly crafted, entertaining and engaging : and absolutely desperate to avoid anything that might offend the mass audience.
Obviously for the developers its all about business - but in amongst all the 'market research' tailored games I'd like to think there will still be some that will be driven by a more dominant creator and will not appeal to everyone as they will take risks with narrative, expectations, etc.
Try to be reasonable... its easier than you think...
