6 years i have played on PC as my main platform, and i have played many games, however only few are listed as stand out's.
I have a video for some of them but not all so will share them.
Skyrim... even if you don't mod it it's still an outstanding game, though people pick fault with it for having a console like UI... well i use a controller so IDGAF :P
130hrs , installed 5 times... (modding experimentation mostly for them installs)
CSGO... though right now i have quit because the game is on a downwards spiral into it's grave.
1006 hrs.
Nothing has come close to the amount of adrenaline that pumps through you being the last guy alive feeling real fear of the unknown, your senses rise massively and you pull off things that would surely get you banned in other games or accused at least.
An incredibly deep game with such mastery that some will never reach.
Battlefield 3 & 4.
I have a love hate relationship with these games, but they both createmoments that no other game can recreate.
Deus Ex Human Revolution...
I don't have a history with Deus Ex prior to this game, but i REALLY enjoyed this games story and art style, it really grabbed me towards the end, and i loved the music!
MW2...
Call me slightly mad but it's the first game i ever bought on steam when it released... it was a fantastic game for it's time just hindered with no dedicated servers, it's a hugely better game vs GHOSTS or MW3 at least, it does not have COD 4's PC finess however with mods and obviously dedi servers.
Oh and i nearly forgot RUSE!
It's a standard affair but i really like it for it's excellent visual style and use of the RUSE system.
Command & Conquer all of them except 4...
The very best of RTS right there!
