I like some of your favorites, my serious games top:
HALF LIFE 2
THE ELDER SCROLLS V: SKYRIM
Grand Theft Auto 5
Against: one that many brings great number of memories
DOOM: This is a classic from the old school
WORLD OF WARCRAFT: A time consuming but entertaining game
CALL OF DUTY: MODERN WAR 2: from my point of view the best of the saga
Uncharted: The 4 Games Are Amazing
The last of us
BATTLEFIELD 4
But a list of 10 games will never be enough...
Exactly! I struggled quite a bit with this list, just due to the sheer number of awesome games that could be put in, there are many I had to knock off (like Legend of Zelda Ocarina of time, FFVII, Battlefield), just due to the experiences I've had with the aforementioned games being slightly better in specific ways.
Of course the list of good games is so broad that it is very difficult to decide (not to say impossible), reduce it to 10 and decide is complicated. Metal Gear Solid V: The Phantom Pain, The Witcher 3: Wild Hunt, Diablo III, Overwatch and the continuous list ... These are very good games in aspects of history, graphics, sound, optimization to say Some.
