For the clueless kids here:

Doom 3 is how iD originally envisioned the first doom game to be, obviously back in 93 when the game was made the tech was extremely restricted both for hardware and software. This has been talked about numerous times in interviews with id.

I wouldn't really say that hl2 has better physics, just that hl2 was based on the gimmick of being able to toss shit around and the physics are far more obvious. Take away hl2's physics and theres nothing special about the game at all.

Resurrection of evil expansion exposes the physics in doom 3 more with the grabber gun. Which by the way isn't a ripoff of the gravity gun in hl2, the leaked doom 3 beta from e3 2002 has console commands that manipulate physics like the grabber so you can pull stuff towards you or blast it away from you. Since halflife 2 like doom 3 was also shown for the first time at e3-2002 it just seems like they were thinking along the same lines with physics manipulation. Both weapons though started off as game development tools so they could mess with the physics objects in the maps.

As for linear gameplay, duh its a fps game, the majority of them are linear, hl2 is linear as well in case you never noticed. oOo:
