I read here and there that someone has beaten thus and such scenario or has beaten level whatever. Is this different than finished? Is there a specific set of conditions to be met in order to beat a scenario?
That is, you have to go from beginning to end
in one session without dying, or
in one session but you can die and continue a saved game, or
in several sessions without dying, but you can save a game, so you can go to school or to work, then continue it later, or
just simply go from beginning to end in as many sessions and dying as many times as it takes.
As an example, I went from beginning to end of Durandal on TC, but it took several months and I died many times, though less often as the game progressed.
Did I beat the scenario; finish the scenario; or demonstrate that I don’t have a life?
Actually, I think that playing Marathon is as valid an activity as anything else people do for entertainment.
