I am still playing Ultima-On-line even after almost 15 years the game came on line. It is by far the most complex game ever made.
I’m not a huge fan of online games due to the fact that WoW took over my life. I founded and ran a 300+ member raiding guild for over a year before quitting cold turkey and vowed to never return to online gaming!
On the other hand, games with massive modding communities are a whole nother story. I have put well over 1000+ hours into The Elder Scrolls III: Morrowind and am still actively playing it. Grimrock, once the modding scene kicks in, looks to be the same along with Kingdoms of Amalur: Reckoning (hopefully, if not it’s still a great game).
Yes, I have no life outside of school and games. My girlfriend reminds me daily of that :D
As long as we’re `fessing up, I play BattleTanx (1999) on a Nintendo 64 occasionally when I feel the need to blow stuff up.
