I'm still playing EVE after 4 years haha, I love it. I don't play as much as I used to with kids now, but it's still great.I am gamer basically last 20 years.
And remember that Diablo, Championship Manager 01/02 and Commandos 2 were really addictive back in the days.
But I must confes that EVE Online got me dreaming about the game, thinking about ship setups, economy, doing extra effort outside the game, like Corporation forum, excell spreeds for minning and profit.
In 2 words TOTAL ADDICTION!
It cost me real money, and I still have account just in case my addiction kicks in
3 years in total
