What game have you spent the most hours playing?

看steam上的统计，在我的库里所有游戏之间，我最常玩的游戏是军团要塞2。我一共花两千多小时打这个游戏。其实，我最初在steam注册账号的原因是我想打军团要塞2，因为几天前游戏突然变成免费玩的。那时我还上小学，在ROBLOX论坛上看别人提到了游戏，也在YouTube上看YouTubers跟游戏有关的视频。

Looking at Steam's statistics, amongst all my games, the game I've played the most is Team Fortress 2. In total I've spent more than two thousand hours playing this game. Actually, my initial reason for registering a Steam account was me wanting to play Team Fortress 2, because a few days prior, the game suddenly became free-to-play. I was still in primary school at the time, and had seen people on the Roblox forums mention the game, as well as seeing YouTubers' videos related to the game.
