javihyuga: And what advantage does this have over playing the original with zDoom or similar? Aside from cards, achievements and whatever feeder they sell as improvement nowadays? Becuase I find the "HD" mode rather ugly.
You're missing the point.
Strife was lost in rights hell, this modern re-release gives everyone an equal chance to legally buy it for cheap and play it. Hassle free and without the ancient DOS-isms. This is a wonderful gesture, and I'm very happy they didn't just slap DOSBox on it and call it a day.
If you have the know how, the will, and the time, then perhaps yes, this port won't satisfy you. To everyone else, they get to experience a lost classic.
