I was thinking today of what my favorite games of all time are, but there are games that I play that are staples, not necessarily "the best". Games I always come back to and it's like a familiar friend, a long lost buddy. Games I can never get enough of.
I have many games I consider staples in gaming, but few I have logged nearly as many hours in as others, so I decided to boil it down to time invested over the years.
It turns out in my gaming life I have invested and returned to "Phantasy Star Online, which is offline also " more times than any other game, even Pokemon or Goldeneye 007 which are close runner-ups.
I owned the Dreamcast, Xbox, and Gamecube versions. I only play the Gamecube version now, and still play split screen with my buddies, and still love it.
I've logged well over thousands of hours on it over all 3 systems, and I find it amazing that I still love this game.
