It really isn't 25 hours though unless if you're skipping thru lots of conversations or something its more like 35-40 imho.
with no walkthroughs or help or anything my first playthrough was about 40, and I skipped a few sidequests, missed the lesbian sex scene (drat), and just starting new game+
i couldn't of done it in 25 if i tried first time thru.
Bioshock, Crysis, & Uncharted.
ic.
none of those really did anything to push their genre or anything. thats why I think Mass Effect is a million times better than them. Crysis kind of pushed MP in the FPS genre to a new level, but man I played Bioshock and yeah, its good, okay, but it does nothing that is going to make me judge later FPS's differently.
ME after playing it, I'm probably going to play an RPG later and go "uh wtf? why doesn't it have [feature ][/feature].
Bio/Cry/Uncharted are good yeah, but they don't do anything mind blowing, and in the industry now you kind of want to go for mind blowing, because mind blowing is the difference between you making lots of $$$, or making decent money, and no one really wants to make decent money cause of how expensive games are to produce now and days. the only exception to this rule is when you know your game is going to sell like hot cakes, where you could probably make the main character have a full detail homosexual orgy sex scene (assuming you ignored the ESRB and sold it in some SPECIALTY STORE that doesn't care about the ESRB) and still sell millions of copies, like Halo.
