1. The entirety of Age of -series, notably AoE1 and AoM! that's my childhood right there, especially AoM. I knew (and kind of still know) nothing about RTS games but being able to create a huge army and specially use mythical creatures of various cultures just tickled that baby autist brain.

2. Destiny 1/2 there are very few games that have fundamentally changed my adolescence quite like Destiny has, and still more or less continues to do so. no matter how little I play it as of right now, it still holds its place as my favourite. and I don't say that lightly.
