Hi,
Id Tech 4 was state of the art when it was released, and still looks good today, but it was ignored by both commercial developers and mod makers.
There's only one commercial game made with the engine: Prey. There are also a few mods (TDM, MITM) and SP maps, but nothing approaching the number or content of UT or HL.
Why's everyone using that broken pile of brokeness, U3?
Is U3 the new Java?
I didn't find the right solution from the internet.
