Vampire the Masquerade - many good times, but that haunted hotel..
S.T.A.L.K.E.R - a lot of brown undies in that one
Playing F2 for first time when I was 13 with vocabulary in my hand as I was not speaking english and being blown out that there are primitives in same world as guns
Seeing intro to Age of Empires for first time, listening to sounds of those units
Finally sending all my tanks one by one to enemy base in Dune 2 only to realise half of them was eaten by worm on the way there
chrusing peons by tower golem in Battle Chess
seeing Skaar in Unreal first time on the ship and those sounds when you step out....
Figuring out that all those followers in Torment are actually following me for many lifes (well at least those inteesting ones)
Playing on LAN parties first DOTAs
playing leagues with friends in CS
Fresh meat! and all that atmosphere in D1
First time playing Morrowind, discovering first open world RPG and how fantastic it looked
All those moments will be lost in time, like tears in rain
