Heroes of Might and Magic III or Fallout 2.

Lately, Lords of the Realms 2. I blame wpegg for that. Quite the game to play and tough to master.

Might and Magic 6-8 are on my yearly play list, too, just like Fallout 1+2, IWD 1+2, Planescape, BG 1+2 or Wizardry 8. What can i say: i love old cRPG's.

Blood! >:D

Then OpenTTD is your answer :). It's Transport Tycoon Deluxe on steroids... and other drugs... and booze :)

Many good titles on GOG, but my FGOATOYMP (favorite-game-of-all-time-oh-yes-my-precious) here is King of Dragon Pass. For a Glorantha lover, this barbarian-tribe-simulator was a dream come true :)

There are quite a lot of challenger for second position, though : Fallout1, MOO2, Beyond good and evil, Dreamfall... But KODP stays first and foremost in my heart.

homm 3 and fallout 2 by far..for now

Really? I bought Dragon Pass on some sale or another and recently installed it but couldnt get into it. I didnt give it any real chance but it didnt immediately grab me so I moved on. I had some trouble finding info on the game as well, I assume due to the age. Do you know of any beginners guides or high level walkthroughs that you like/?

Some ARMA part, currently ARMA Gold (I could never get myself to play the whole campaign through). I also have ARMA2 with all addons from Bohemia Interactive directly, wonder if I could redeem the codes here with all packs?
Arma 2, Operation Arrowhead, British Armed Forces, Private Military Company, Army of the Czech Republic

I know they have Arma 2 with OA as a pack on gog.com

I don't know any guide apart from the manual+tutorial combo, sorry. That said, that's one of those games where reading the manual and the reference card before playing is mandatory : Most game concepts are explained in it, and even the tutorial is inside (it's a chapter of the manual that will guide you for 1 in-game year with a preset game). Perhaps more importantly, it presents some cultural background to the player that helps to get "in a barbarian cheftain's head". That sort of roleplay is kinda necessary to get into the game, you don't get far if you think and react like a 21st century civilized westerner.

My love for the game could be due to the fact I knew the gameworld from my runequest (pen and paper RPG) days, so it's like a stroll in a beloved scenery, but I find it quite unique and immersive.

Hotline Miami

Another one I had interest in. What was the appeal for you?

Absolutely. I don't even remember installing OpenTTD it just magically grows on my computer like psychedelic mushrooms. I knew Transport Tycoon was dangerous (even the classic version) ever since I lost a ski race after pulling an all-nighter with this game 20 years ago, knocked over all the flags and placed last. At least no one got hurt, this can't be said about other drugs like alcohol etc.

Hotline Miami is not my favorite game here but anyone who claims it is I WANT TO HANG OUT WITH! :D That thing is so bizarre and twisted for so many different reasons all of which make it one of the most unique looking and sounding games around.

Master of Magic

It's a tough call. There's plenty of games on GOG that I had played in yesteryear (Tropico, Caesar 3, etc). But as far as games that I bought and played ONLY on GOG, it would probably have to be either FTL or Eador - Genesis. I still play both and am digging the FTL advanced edition.
