I think you are mixing things up here. Beneath a steel sky was not made by Sierra. The engine was also not used for King's Quest 5, but rather 6 and Broken Sword 1-2. Gemini Rue uses an entirely different engine called AGS.

I haven't beaten the majority of my GOG games. In fact, I haven't beaten the majority of the games I own, period.

I am actually concentrating on my CD based games now, not GOG games (maybe I consider GOG games a bit safer to be left played "sometime in the future" than CD games). I think I haven't yet beaten even the first GOG game I've purchased (not counting some which I may have completed already before I bought from GOG), and I've purchased most games on the GOG catalog now.

Currently I'm stuck in trying to kill Diablo at the end of Diablo 2 Act 4 (and then I'd continue to LoD Act 5), and some extra hard mission in Heavy Gear, was it mission 23 (I don't get it, one of the enemy gears uses some kind of homing missiles that kill both my team mates and me with first hit, how exactly am I supposed to kill that bustard? Dunno, maybe there is a small time window to attack it from the side when it is mercilessly killing the rest of my team...).

Out of 54 games (actually 67 because of packs like Might & Magic) I've beaten 18.

Arcanum
Beneath a Steel Sky
Broken Sword
Dragonsphere
Fallout
Giants: Citizen Kabuto
Guilty Gear X2 #Reload
Fahrenheit
Lure of the Temptress
Might and Magic 3: Isles of Terra
Planescape: Torment
Raptor: Call of the Shadows
Return to Zork
Sacred Gold
Septerra Core
Teen Agent
Two Worlds
Tyrian 2000

I buy games faster than I can play them. I've still barely touched any of the games that I bought during the last Christmas sale.

Out of some 80 GOGs (which includes bundled games) which I hadn't beaten before getting them on GOG, I've only beaten the following 16:

Gothic 1
Flatout
Redneck Rampage
Shogo
Beneath a Steel Sky
Second Sight
Teenagent
Sanitarium
Another World
Alien Shooter
Simon the Sorcerer 1
Simon the Sorcerer 2
XIII
Chaser
Rayman 2
Rayman 3

And its far worse with my Steam games....

Oh, after re-reading the original thread (after reading Kalirion's bold text), I realize that I might have misinterpreted it a little.

I've not bought a single game on GOG which I previously owned. I did own Beneath a steel sky & Ultima 4 though, and had beaten them before joining GOG.

I finish most of the shooters and RPGs I buy. When I get games in other genres I like less, such as point and click or action, I tend to take longer to finish them or never finish them at all.

This holds true on GOG... most of the shooters and RPGs I have here I have finished at some point in my life. The others not so much.

I tend to finish the games i start, the once that i found not fun enough or not good enough to continue for me personally where: gish, and yet it moves, and world of goo. Deus ex invisible war got very close but i stuck to it and finished it eventually

I can believe that, I've played BG2 about the same number of times.

Yeah, I think I've misread the first post as well.

The following GOGs I've started (and put at least an hour in), but then stopped playing:

Rayman Forever (too hard, I may complete some more levels but definitely not Mosquito's Nest w/o cheating)

Baldur's Gate 2 (stopped playing before the finale for some reason, will likely restart at some point)

Descent (got too hard and annoying, I still occasionally play it a bit to see if I can progress)

Beyond Divinity (got too annoying)

HoMM 3 (was taking too much time per scenario, I'll probably go back)

Ishar 1 (I'm not much for making my own maps)

Blake Stone: Aliens of Gold (will probably come back at some point)

Rise of the Triad (see above)

Expendable (couldn't stand the controls)

Aquanox (see above)

Arx Fatalis (too hard to id the loot)

Stonekeep (just stopped being fun)
