It’s certainly not from a lack of user interest. Search terms like “facebook alternatives” have absolutely skyrocketed to unprecedented levels in the last couple years
Your certainty will be the mistake here. What does “skyrocketed” mean? From 10 search requests to 100? J/K. But: Is it more than the 1% of users? I doubt it. Most people are not interested at all in stuff like this. They go where everybody is, simple as that.
So go figure: 
true. But in hindsight, both were awesome with different aspects. Half-Life had a much more long-lasting experience through its modding capabilities - and an outstanding story. Unreal was visually and technically beautiful and had a mind-blowing athmosphere - but of course a single player game isn’t as longlasting as Half-Life was. (I know it had multiplayer, but at least in my perspective this was not Unreal’s focus - which changed dramatically with Unreal Tournament)
soulmate. I liked it as well. Of course it wasn’t groundbreaking, like Duke3D was, but it was fun. And it made fun of itself - I like that trait.
What? Who didn’t like Unreal? It was groundbreaking, a milestone of its time. In my area and peergroup, everybody loved it.
Wow, that’s late.
Constantly filming in public IS pervert.
