I am a proud member of the PC master race. Last console I owned was a Sega Genesis. I played a PS1 at a friends place a few times, a PS3 for about 30 mins and I've played xbox for the first time a few months ago, again for about 30 mins. I think it was a 360. I just cannot stand controllers.
I used to play a ton of strategy games and RPGs. Not much on that front these days. My favorite games are Gothic 2, HoMM III and V, Warcraft III, and I like Civ V quite a bit. Recently I've been playing a lot of FTL with brief spurs of Path of Exile, and in the last few days, Diablo 3. Patiently waiting for Witcher III and the FTL expansion.
I play on a gaming laptop as I moved over continents recently and, well, needed to buy a gaming rig that I can bring along with me. It's okay and all, but I can't wait to build a proper rig once this laptop gets behind the times.
Gothic 2, great game. True diamond in the rough. But once you got over the flaws, it was great. At the time i ranked it in my fav rpgs ever but it was knocked down some positions since (notably by Oblivion and Kingdoms of Amalur). I have to say i never tried the Gothic games after that (and whats that other similar series the publisher started after...forgot the name now.. i think it had some people from gothic working on it). They were released with loads of bugs and i never tried them after the patches.
And like you i'm anticipating Witcher 3 a lot. To be honest i tried the first one and couldn't get into it. But now this is going to be real open world... I think i could really like it.
Heres a few of my fav games of all times in no order since i didnt make a list before. Im gonna try for a top 30 but including series as a whole when it applies This goes as far back as the N64. I played snes and NEs for years to death but i don't know that many games in there could realistically still crack my top 30 games of all time... even on the strength of nostalgia.
Elder Scrolls series (though thats a liem i played oblivion and morrowind, never skyrim and none before those)
GTA Series (San Andreas as the best but i have yet to play V)
Medieval II : Total war
Crusader Kings II
Europe Universalis series
Just Cause 2
Freelancer
Wing Commander: Privateer
Ultima VII: The black gate
Ultima Underworld
Test Drive Unlimited (the sequel is one of the worst sequel ever in the history of gaming, i played TDU to death and im not a driving game kinda guy normally)
Kingdoms of Amalur: Reckoning
The Saboteur
Hitman series
Saints Row Series (except maybe the fourth...)
Far Cry (hated the 2nd, loved the 3rd until about halfway when it became too repetitive)
DC Universe Online
F Zero X
Goldeneye
WCW/WWF THQ/Asmik wrestling games series
The Legend of Zelda: Ocarina of time
Metroid Prime
Eternal Darkness
Halo and Halo II (never played any after that...)
Red Baron
Doom (kinda have to...landmark game)
Carmageddon
The Sims 2 (and probably 3 if i ever play it....)
Minecraft
Assassins Creed IV
I think that's 30. And pretty much the best of gaming in my world from 1990 (Red Baron) to 2013. A top 50 would see more older PC games (maybe the Sierra Quest series for one, and wing Commander proper) and Nes (river city ransom, Iron Tank, Castlevania II) ans Snes (F-zero, Star Fox, Street Fighter II, Mario Kart) games as well.
Edit: Just thought of Mount and Blade. I should kick some other game off the top 30 to replace it with that. I knew this would happen.
