Free/cheap roguelike network games (a la Diablo II) for cross-platform, long distance relationship gaming date night?
My partner and I have been trying to find a good, low investment dungeon-crawl type game that we can play together to while away the last few weeks* of a long long-distance relationship. Some relevant details:
We want a Diablo or Diablo-like dungeon crawl that
1) can be played by two players over a network where one player has Vista, the other OSX, and both Ubuntu Linux
2) can be obtained legally via a download
3) is more cooperative or PvE than it is PvP
4) is cheap or free.
We're many miles away from each other, but both in the continental US. I'm comfortable with running a server on mine, though neither machine is really a powerhouse. Are any of those "free" browser-games that worth playing without paying for the downloadable content?
