There is only one thing i could agree partially:
You could compare them to Quake 3's or UT99's graphics, with some extra special effects.
Well... that's this point and I'm still not clear "how" to agree but mainly I do.
Fact: Nexuiz has tons of special effects like Bumbmapping, Deluxemapping, Realtime shadows etc. that drive even my hardware nuts.
BUT: (and don't see this as stupid critic) If I only look to it as a "normal player" without technical background I could say:
"Nexuiz eats my hardware but Doom3/Q4 RUNS AND LOOKS BETTER on Max Details."
If I look back to 1.21 I can fully agree to this statement and even in 2.0 in some points.
But please don't get me wrong: The game is superb.
Nevertheless we know Nexuiz needs new models. And on this point I can agree the statement above:
At least the models still look like UT99 with "some improvements". Compared to the models in todays commercial (highlight commercial, which is Nexuis not) shooters they do not win.
I would also say the same to the levels. The levels ARE COOL, especially th light effects - BUT try to compare them with the "details" of an UT2k4 level...
Again - this is NOT meant as critic to Nexuiz after all. As said, levels, models can't compare to commercial games, but those games have teams of (good paid) coders caring about this stuff.
We should keep in mind, Nexuiz is free (no money, no closed source) and for this we have a VERY nice game.
