Most addictive single player game

[darth jacen]

TES IV: Oblivion and Bioshock for the same reason, I loved exploring the world and just living within the atmospheric and immersive levels.

uhm, for me the most addictive is probably heroes of might and magic 3, closely followed by games like civilization, total war and hearts of iron. online i only play games that are online by nature (mmorpgs) and the rest im only itnrestedi n singleplayer (thus very dissapointed whne you spend 20 euros on a 4 hour game with 0 replayability *cough* red faction 2 *cough*

Dodonpachi or Mars Matrix plus any other good Japanese shmup.

Psychonauts.
...
Not much more needs to be said on why, It's Psychonauts.

That does it. I am now going to the Steam Store and buying that game. I just keep hearing good things about it.

'Tis true that 'tis good, but beware of the meat circus my friend, it may break you.
