Thanks everyone for the support etc. I thought it would be useful to the members, what with everything else being in one place too (i.e. 100% Offline etc). Plus a lot of people have been asking about co-op games and I know I sometimes ask around for what to play with friends online.
Obviously it's going to take a while to fully complete but I will get there and thanks to people who are giving me games to add to the list. Some I only know because of my collection etc, so again thank you.
