I used to play computer games much in my childhood.
For a while I was very good in
=> Quake 3
Of course I liked other FPSes much, like:
=> Half-Life
and id Software classics:
=> Doom
=> Quake

=> Fallout 2
Took the most part of my game life. I believe I spent more time on that
game than on all of other ones summed up!

But later I beloved adventure games and quests. My favourite ones are:

=> Grim Fandango
    (one of the best adventure I have ever played)
=> Monkey Island 2: LeChuck's Revenge
    (also one of the best quest)
=> Secret of Monkey Island
=> The Longest Journey
=> Curse of Monkey Island
=> Full Throttle
=> Day Of The Tentacle
=> Cat Lady
    creepy, horror
=> Downfall
    ultimate incredible unbelievable sick maniac experience!

Most of them above could be played in free software
=> ScummVM

From time to time I also play
=> FreeCiv
=> NetHack

Who is the loveliest and most adorable girl from the games?
=> April Ryan

I also liked
=> Magic: The Gathering
