My Steam , GamersGate and Telltale accounts . Too many games too little time . :(

Valve are actually really good at finding out an account was sold and shutting it down. The market for such things is pretty small in my experience.

Not really allowed to sell those accounts

Good thing you are going to keep your GOG account though. Or did you sell it already? Who am I talking to anyway, are you even the original ne_zavarj?

Is this real life, is this just fantasy...

You called ?

I know i can't sell these accounts . I just watch the lists of games that i own , and realised that i spent too much money on them in the past years .

This is one thing that I never understood.
"I quit playing games/WoW/xyz MMO/etc therefore I must sell my account"
Don't be an idiot. If you end up selling your account it will be at a massive undervalue anyway. Just keep it for when you snap out of your mid-life crisis and if the temptation is too much for you to handle, give it to a fellow GOGer who can look after it until you feel like coming back.

Beside the legal problem I don't believe to discard all your accounts will really help you, after some time you will miss some games and then restart buying them. Maybe some suggestions before you're doing such a drastical move:

If you use wishlists,clean them up and keep only games you really (really!!!) want and will play shortly after buying them. Also cut down the information channels that let you trigger to buy new stuff - if you use rss-feeds or newsletter, unsubscirbe some of them. Also set yourself a very restrictive maximum price point, as example 5$ or even less and maybe also a maximum budget each month that forces you to rethink every purchase at least twice.

Actually there is a huge market of Steam account, if you know where to look that is. However the price of these account is not too high, as the buyer can't be sure you won't recover it after you have the money. And recovering is super easy, all you need to do is to email Valve, answer few questions regarding your lost account and provide them with some photos/scans of physical copies if you've got any and/or emails from digital stores with your serial numbers.

Exactly. There are a number of games I regret selling due to not having enough time / space for them. Or thinking I'd never want to go back to them again. With digital downloads (aside from the company going out of business) this is less of a problem as you can just leave the games on those accounts and come back to them as and when you want to.

I've never understood that giving it up kind of thing. I've never heard of anyone giving up books or movies because they take up too much time.

I've played around 30% of the games I bought? I don't see this as a problem, cause games are men's shoes and dresses. I buy them, because they looked nice / caught my interest.

I will play each one of them... someday? :P

I buy too many games too but I don't feel bad about it. The cheap sales prices are a big part of my buying habits but so is the instant access anytime I want. Just because I don't want to invest 60 hours in a massive RPG right now doesn't mean I won't want to in 6 months. Yeah, I could wait and buy it when I really am tweaking for one, but who knows if it'd be a decent price then? So while I might've been 7 bucks shorter that week, I'm probably 20 bucks better off in the end when I decide to pick it up. This isn't a made up example either. Bought Warband and Avadon a handful of months ago and have just started playing them the past two weeks and have put in far too many hours to be healthy.

Now, if you buy a lot of games and you flat out hate some of them, then it's time to rethink.

I didn't really think such emotions are possible. Intriguing.

I'm joining the group that thinks you should just hang on to your accounts and severely limit your future gaming expenses. Selling your accounts would actually really be a money waster IMO.
