I'm relatively new to GOG. 3 out of my 9 games are completed (I don't count the free GOG-Games you get with registration). But I think I will complete more soon.

On Steam it's probably 25%. On gog I end up picking up a lot of grand, sweeping old RPGs that take 100+ hours each.

So here on GOG it's probably more like 2 out of 55 (3%?) - I think just Defender's Quest and Spellforce 2, neither of which are particularly hefty time commitments. Admittedly, some of that 55 includes the freebie games many of which I don't really consider to be in my backlog at all.

Edit: Now if you expand that to games I've completed more than 50% of it's probably more like 10 of 55. Still really need to polish off Divine Divinity and Blocks that Matter, but so many other shinies competing for attention!

I am not so good with higher mathematics but if the chaos theory is right than i believe that one completed game is a direct way for completing them all.....that or a shortage of alcohol

I will never play all the game I have (and I will have in future).

Speaking of which how do you organize stuff with tags, as of now tags dont seem to be available. I cant add anything to the tags section.

Open your library. Click on a game. Select the "more"-button and choose a tag. Now it is tagged. You can use the tag button (right corner of your library) and activate one of your tags. You will see the choosen ones.

Just got it, thanks. I was starting to think that it was an upcoming feature.

3-4% give or take (including the ones I finished years ago).

93.1% completed.

I've included games that I won't play or won't continue as games completed.

I try to have more than 75% completed at any rate. I only buy games that I know I will play in the near future, not because they are "must haves". The fate of must haves is that they often sit on the shelf without ever being installed on the computer.

With such big game shelfs its the same as with a huge amount of books in a library:
They bend the space when there are too much in one place - so when you finished one it could be that you finished all
But it could also take infinite time - or it could suck you into a black hole..

.
Especially after such a summer sale (and the Starwars sale earlier this spring) Im glad when im somewhere near 10%

Don´t even dare to ask for that...
...even my tryout-rate is probably below 50%! But that´s no problem---I´m building up some pretty decent "security wall "so I could even continue gaming for years if GOG dies---which gets less likely with every purchase we do!

61/149 (41%)

(Game boxes I've actually finished/everything else)

32 games completed (few which I did before GOG but purchased just so I have gog copy)

out of 125

25.6% is my ratio.

ack. i can count them on 1 hand.
