Why spend so long remaking a game when the first game is perfectly playable and readily available? Bizarre.
I don't know about anyone else, but I'd rather spend my time on new experiences not old ones.
Be mindful of your surroundings. That's very thin ice you're treading on, especially on this forum.
Silent Thread Reborn includes new and revamped missions, it's not analagous to Black Mesa
SCP is updating the code and adding new features, same deal.
FSU is just a HD upgrade to the original game and benefits many other mods, again, not analagous.
so FSPort wasted their time then?
I love how people always get defensive, put words in my mouth and jump to the worst possible conclusion.
FSPort didn't waste their time so long as they enjoyed what they're doing.
But for myself personally, if I want to play FS1 I'll play FS1 not FSPort.
Similarily if I want to play HL1 I'll likely just play HL1, not that I'll play HL again anyway. Since Valve decided to stop making SP games I decided to stop caring about HL2E3.
If Valve put it up for voting, I think Valve's okay with selling a remake of one of their games on their distribution method. 
Er, well there are three options for Valve:
1. Issue a C&D and take a huge PR hit with the rampant fanboyz
2. Let it be distributed as mod and get nothing for it
3. Put it on Steam and rake in 30% of the profit for zero work.
If you were Valve which option would benefit you most?
