I noticed on many people's profiles, that in the "SteamID" field, they put things like "WTH is Steam ID?" or "I don't know what that is" or things like that. Simply put, your Steam ID is your Steam profile name.
What is Steam? Its a gaming platform where a bunch of computer games are sold and played on (store.steampowered.com). If you don't have a Steam account, then you don't have a Steam ID. If you do have a Steam account, then it is up to you if you want to fill your Steam ID or not.
Steam ID backwards is DI MEATS! Anyway, yeah I have a Steam ID: Joe2496 It's pretty cool, because you have free multiplayer access and to top it off, on your computer! ... I don't think I said it right...ON YOUR COMPUTER!!!
Everytime i delete my SteamID my ArmorGames name appears there automatically >.> My SteamID is different than y name on here, i just don't use it so therefore don't see the need for it to be on my profile.
