I rather pay 20 for 6 month. I am a person who never touches a game again after finishing. I also never go to the cinema twice for a movie. Its the aame movie. For what? Its like sex. Always the same position is quite boring.
Well i agree there. If you never play the game again makes sense.
I personally like to revisit games and with a hectic work schedule sometimes it takes me 4 to 5 years to finish a single player game these days.
