The best old game i've played when i was very young was counter-strike 1.6, i remember the day my uncle bought that game for me and oh god i've became addicted to it for a while, team work, communication, fast-paced shooter, it's like the wonderland of fps video games, no matter old it is, it is playable to this day, infact lots of people still play that game because tactics and ideas don't run out, the way maps are made is totally calculated which i really think valve did a pretty good job on that one, so yeah maybe you'll get to know this game, might as well tell me if you like it or not.
