The most addictive game

JA+ and base

Heroes of might and Magic
Disciples
Unreal Tournament
Mount & Blade
NFS Underground 2
Tekken 6 (PSP)

RPG game for me is the most addictive

Final Fantasy 8 sucked for 2 years, 5 times was probably.

Civilization 5, Quake 3, Heroes of Might and Magic III, FF Tactics, S. T. A. L. K. E. R. PM and a scattering old PC only RPG.

Mafia 2,GTA SA

Dark souls 2,3
Stalker 1,2,3
Metro of 1.2
Swkotor

Euro Truck Simulator 2

Rocket League! Bought for one night to play. In the end, she acquired all his friends and favorite over 90 hours.

The Elder Scrols Skyrim !!! 1075 hours of willfully

there's a difference between playing constantly in something like DOTA, CS, and meanwhile to run the game and get stuck for 20 hours a day, it's games like Civilization 5, Jagged Alliance 2, Euro Truck Simulator 2, Stalker, The Binding of Isaac

Well, purely my opinion.
1. Series Crysis.
