Hmm, this is a hard question. It would really depend on the quality of the mod when it’s released - but if it is quality and faithful to the original and the changes only serve to improve the game i might say yes.
Here is the wierd part, I HATE remakes of most things. Most of my favorite games i love to play with their old graphics, especially the 2.5d ones (ala Doom, daggerfall) But for some reason, i feel half-life would benefit from a remake. I have no idea why, but if this was for ANY other old game besides half-life that i liked, i would most certainly say no.
