70% of the people don't finish their games? Could we also say that 70% of the games are not worth finishing? Maybe that's the thing I would want to see in a game review ... is it worth finishing, did you play all the way through?

As far as choices in story options, I tend to stick with the heroic path most often. The replay value is more in the way problems are solved and skills are used, whether it be conducting combat, or getting NPC's to do things differently, or finding out hidden information. For example, I recently made a Shadowdancer in BG II and wow, I love backstabbing now! Before it was always a pain in the arse to have to run away and back, but with hide-in-plain-sight it became really fun! Take that, Amalas, you lout!
