all games are not created equal

I have played through both, and I enjoyed bouth thoroughly, but I feel my experience in Dead Space has been more enjoyable. Both weapon upgrading systems are great, and the atmosphere that both games create is amazing. I have to say though towards the end of both games, Bioshock started to get annoying, and I found myself just wanting the game to be over, did not feel that when I was playing Dead Space, let me know what you think =)
