Surprisingly awesome games?

I played a little over an hour of Dead Space and I just was not getting into it. I know it is something I need to give a serious try again at some point in the future, but I have little to no motivation due to how underwhelmed I was with my first go.

regarding the question of a game I underrated that surprised me, I can't really think of anything except maybe The Misadventures of P.B. Winterbottom. I forget exactly why I got the game(could have been due to it being 49 cents a couple winter sales back) and I ended up enjoying it so much it became the game I gifted to a few random friends for the fun of it that year.

Just to put the corkscrew in, Dead Space isn't the first game I've had like this. Some other games I didn't have too much of a high opinion on (which are all incidentally some of my favourite games of all time):

• Psychonauts (Seemed rather childish and pretencious, a lot like me)
• Alice: Madness Returns (I saw the Yahtzee review before I played the game...he is SO WRONG)
• Ratchet & Clank 3: Up Your Arsenal (Couldn't make it through Florana on my first go...)
• Spec Ops: The Line (Even after what everybody had said, I kept the opinion it was just another brown modern shooter)
• Bastion (I used to hate indie games a lot)
• LIMBO (Especially ones I thought were lazy)
• Beneath a Steel Sky (NOTHING COULD BE BETTER THAN SAM & MAX?! EXCEPT THIS?!)
• Bioshock (I thought it was pretentious before playing it, but it turned out that it was actually me being the pretentious one)
• Mass Effect (Careless deaths that were my fault frustrated me in the first one, but I was especially cross at ME2 for an hour with the changed gameplay)
• Half-Life (See Bioshock)
• Assassin's Creed II (Ubisoft)
• Dishonored (Thought it was going to be lame attempt at copying Bioshock...so very wrong)
• Uplink (Simplistic interface and challenge over story?! Who could enjoy that?!)
• Freespace 2 (I thought space was boring for a while, until they brought on the SJ Santhanas...)

As you can probably tell, I'm quite a negative person...
