My Top 10 (because everyone has to have one)
Because everyone has to have his personal Top 10 list sooner or later, I've decided to make one now.
Keep in mind that this is my personal list - there may very well be some great games besides these, but I never played them, they didn't have a big impact on me like these games did or they just weren't made for me.
16/09/2010 - League of Legends and Mass Effect 2 replaced Indigo Prophecy and Psyhonauts on spots 9 and 10
16/12/2012 - Cop out time! I have expanded the list to over 10 titles. Treat anything below 10 as a "honorable mention". Journey came in and games from #5 down have been reorganized.
