Heroes of Might and Magic III
World of Warcraft (before third expansion)
Team Fortress 2 (before mannconomy)
And by 10/10 i don't mean perfect, but games that made my jaw drop when i first saw them and i ended up playing them for many months if not years before i got tired of them, if i ever did. Basically games of my childhood, that i will have font memories of for the rest of my life. And i yes, I'm a blizzard fanboy if you didn't notice, though not so much anymore.
