Game And Downloads


So i got a few question in mind:
1. Is LS only able to play games downloaded from Steam only or it also able to play games that you download from other sources?
2. If i download a game, like Warframe for example, will it consumes my data or it will use the servers data to download it?
Note : Sorry if my language is pretty bad.

  1. You can play any games you want as long as "windows" could run it. and ofc you must own the game, idk if you can use cracked games.
  2. LS will use their own data in order to download it.
