I dont think so..it adds more to the game especially those that are finished in under 10 hours. It add challenges and replayability; most of them are stuff you wouldnt normally due after you complete a game. 

out of the ones I have so far I guess it'll be World at War mainly because of the mission Heart of Reich....so many hours spent trying to beat that level on veteran....damn grenade spams

I wasn't expecting it at all...but I ended up getting it when I came home from Spring Break (and a nice surprise at that!). When you least expect it you will receive it.

1. Bioshock Infinite

2. Batman Arkham City

3. Witcher 2

I LOVED every minute of this game...I finished it 100% already....I'm excited for the  DLC !

Today I am going to try and finish of Bioshock Infinite on 1999 mode. After that I should be finishing of Dead Space 3 on Classic Mode so my roommate and I can star co-op. 

despite beating Demons Soul I downloaded this because I left my disc version at home...this is an amazing RPG and is really fun co-op

both are amazing games, but for me its Bioshock Infinite...going on my third run now and get the last two achievements I need (both 1999 mode ones)
