a nice recreation of a classic
graphics - there are pretty much the same with almost nothing different. (great)
sound - I can't really see much different with the sound (mostly because the TV was on mute and we couldnt change it)
I'm gonna guess they kept it the same so in that case the sound is great.
gameplay - now the controls are a little weird, you kinda feel like you're gliding around and not really walking because you just don't walk realistically. The same thing happened with DOOM but if you played any of the older ports with proper controllers, keyboards, or anything like that than you should be fine.
final feelings - if you're a seasoned gamer than this shouldn't be a hassle to play and because this was pretty much the pioneer of the FPS you should at least respect it if you like halo, COD, or anything of that nature.
This is a classic that must be played, and or respected.
The only problem is a "floating" feeling when moving but if you can get used to it and if you played any of the older ports than the controls won't be a bother (even at the beginning).
