I just built a gaming PC and downloaded ubuntu linux. I do not have a wireless adapter, nor do i have a router in my room. So what i did was go into the room where my router was and downloaded steam, google chrome, and all of my games that work on linux. I then took my computer back to my room. I chose to use steam in offline mode. However, whenever i try to open a game (ex: metro last light) It opens it for a split second, and then it disappears. It says I last played the game today. I just want to know why it wont let me open my games.
Note: this is happening with all of my linux available titles (witcher 2, euro truck simulator 2, metro last light, and trine 2)
