Well, thank you to those people that I got posts from stating their favourite games and I did receive more than 24 in the process and decided to include all of them in it so if you didn't post in the comments section, then it is too late since I am only taking the ones that are there now.I received a few of the same games but on the different versions like Doom 3 (PC) and Doom 3 (Xbox).  It doesn't matter what format it is on as it is still the one game.

This looks like it will take a while but I will do one or two each day and the the winner is the one with the most votes in the end and will progress onto the next round until we have a ultimate winner. 

Good luck and start voting for your favourite.  You cannot vote multiple times now on a match.
