Yeah, UT is much, much better, but the original Unreal definitely wasn't garbage either. It just wasn't a killer app when it comes to gameplay.
There's also the fact that Half-Life completely overshadowed every FPS launched around these times: many other quality shooters released near that date like SiN and Shogo never got a chance because Half-Life just grew so big.
I'd take a shooter with heart and character like SiN or Shogo over any of the generic bald space marine/thug that we have nowadays. It's depressing to see a trillion games that all look either like Call of Duty or Blacksite: Area 51.
But that's modern games for you. When games cost so much to make and there's so much competition, you can't afford to make a risky project that could crash and burn and make the editor lose 20 millions.
Because of that you don't give a shit about owning original games anymore. In these recent times the only games that I truly felt proud to own were SMT Nocturne, Neverwinter Nights 2, Vampire The Masquerade: Bloodlines, Minna no Golf 5, Virtua Fighter 4/5, Dragon Quest VIII... and that's it. These last few years have been depressing and mundane as fuck.
But in 1997-2000 that was a wholly different thing, I was proud to own so many genuine copies of games. It seemed that every quality game had some unique trait to it. I think that the amount of storage brought forth by DVD combined with the insane cost of modern game development killed our hobby as we knew it.
