Counter-Strike 1.6 / Counter-Strike: Source / Counter-Strike: GO --- Combined to over 5,000 hours
All of the following games I also have at least 1,000 hours in: Command and Conquer: Renegade League of Legends Runescape Starcraft 2 Team Fortress 2 Warcraft 3
I normally find a few games that I love and just play them. I am not someone who buys hundreds of games or goes all out on steam sales. I normally play 1-3 games at a time, and I play those games for months to years.
