Most Annoying thing with steam?

Steam is pretty slow.

Hard Drive usage, jesus fucking christ...

• The fact that when you have a lot of games, activating a key freezes the client for a while.
• The fact that you can't activate a key from the web like Desura (makes me miss all the ninja key drops while at work)
• The fact that the games icon's don't seem to be cached in the client and that it constantly reloads them from the site. (When you've got over 1k games, this really takes forever)
• The fact that you can't tell Steam to not automatically update ALL your games at once, and how badly it behaves when automatic updates are turned off.

i also get the problem of "no connection" frequently, and when downloads get suspended :/

• Inability to chat while verifying game files
• Slow Client
• Inability to open multiple tabs in client
• Unequal region prices ($1=/=1€, other stores don't stop you from buying in different currency)
• We don't actually own the games
• Inability to play games in offline mode that require updating

I agree with you, it should be fixed.

Big picture is useless, IMO.

Having to install DirectX pretty much every time I install a new game.

1- Support is retarded

2- Region locked games

3- Support is retarded

4- Client bugs while activating a game or checking game files as you said

5- Support is retarded

6- No Turkish Lira support, 1$ = 2 TL. Our average pay is 773 TL.It is impossible to buy anything at full-price.

7- SUPPORT IS DAMN RETARDED.

Steam has so many freaking problems as a software, as a service Steam is great, but as a software it's simply horrible.

EDIT: And support is beyond hopeless, by far the most terrible support I've ever seen.

this

another one: you can download only one game at the time

U cant download game while playing some other(singleplayer) game.
There is a workaround but still,it makes no sense

I can deal with support, cache, verifying, regions, $1 = 1€ etc, but the client sucks so bad. It's so freaking slow, it's so damn glitchy and buggy.

Can't put games into multiple categories. I'd love to tag my games.

Most annoying thing? Every time I leave any game it get stuck and stays like that for 2-3 minutes... :|

Ability to check if a key is used without using it! >:(

Also, ability to turn keys into tradeable/giftable copies.

enter date of birth on steam.... i mean seriously? WHO IS THE IDIOT WHO SAYS THAT HE IS UNDER THE PEGI FOR THE GAME HE WANT TO SEE? :(

The flaky "offline mode" that doesn't seem to work unless you switch to offline mode while you are online. If your internet is down, or you play on a laptop and you're travelling, you might try to start Steam and it will say "Would you like to start in offline mode?", after clicking yes you get an error that you cannot connect to Steam and it shuts down. Offline mode. Right.

Support by far, i cant remember have i encountered a worse service somewhere else, either it didnt existed or it was way better that this abomination that Steam just refuses to improve. At this point, i can only recommend to any new user to consider Steam as no-support platform and if he encounters any issues he is better off fixing them on their own any way he can.

I wish you could categorize your friends. I have a bunch of people I added for trading etc, but I don't always want them on the top of my list.

The horrible 'friend and group' finding system.

Paying in Euros.

The fact that they have no random game button. Going throw my library is to boring, I need a button that can throw me into a random game in my library.
And, can't believe I forgot this. The mobile apps look like complete utter garbage, especially the tablet ones. They just took the phone versions and stretched them the fudge out.

May be just me, but steam overlay crashing every now and then

What I find annoying is that you can't play while downloading. Although you can minimize the game you are playing and download the game, but it keeps on pausing. What happened was that I needed to download Portal 2 on my slow internet, but I was bored so I wanted to play the ship (I was that bored). But I had played the ship and at the end I found out it had paused >:(
