Federal Agent Area 51
Faced a weird bug on Steam for Linux(Ubuntu 14.04 LTS). I was playing matchmaking and CSGO and the game was somewhat lagging(network issue) so I thought I'd disconenct and reconnect to fix it.
I disconnected and the whole game froze, couldn't move mouse etc. Alt+Tab didn't help much too. I tried starting terminal etc and didn't work. I directly turned off the power(using a Laptop btw) and after the next boot when I ran steam, all my games were gone. There were only "Install" buttons. On checking the directories, thier files were gone too. Oh well
It's actually a little different: Information about Game Collector Badge / XP per game owned :: Steam Trading Cards Group
What are the other ways of getting xp other than creating badges ?
Buy games: there are badges rewarding you for owning x amount of games.
Complete card sets: you can get a total 500 xp for completing a card set 5 times. You can complete a card set for under dollar depending on the popularity (most source game card sets will run about a dollar).
Complete FOIL card sets: you can get 100 xp for completing a card set at a maximum of 1 time. Foil card prices can be found for under fifty cents each, or can run you $15+.
Be here forever: you might see people with high levels and not have completed one card set. That's because Valve highly rewards Steam Veterans. You get 50xp per year you've been a steam user. 1 year = 50 xp, 2 years = 50 more xp, and so on.
Complete "Special Challenges": Complete tasks like Summer Sales or Holiday Sales or King of The fort! You will find a nice amount of xp waiting for you.
In all honesty, the more money you spend, the higher level you will be.
