I'm pretty sure that the majority of people surfing here had experience with video games at a certain period of time in their lifse on a certain console or pc .
So what was the game you liked or spent time playing it the most ?
For myself it was counter strike 1.6 .
Same as you, Cs 1.6. I spent years playing this game, good old memories
After that, I'd say Lol or Dota are really good f2p too. Lot of differents gameplays with all the characters available.
