Well was looking up some postal 3 stuff today and found out that postal 3 engine is using orange box engine developed by vavle . do you think the engine will make the game better ? well love the source engine and own many games of it . what do you think ?

It uses the Source Engine not the Orange Box Engine since there isn't one.

Yeah theres 2 different engines i know , for example css uses source engine , ep2 , dod:s tf2 and most other mods/games use ep2 engine/ob ( orange box engine )

Bleh nevermind brain fart. You are right.

It's supposed to be coming to Linux, so hopefully it's not some crappy Wine port, and they actually get a native Linux client.
I really do like the Source engine though, and Postal 3 looks great. Definite buy.

From what I heard it was supposed to be the first Source game coming to the consoles. So that means a set release date was before the Orange Box's release but I guess something happened and it got delayed. It sucks, but what I'm concerned about is they are going to use a 3rd person perspective instead of a first person perspective which kinda worries me. I love the game being in first person rather than 3rd person.
The Source engine might make Postal better. It's an old engine but you can still get a lot out of it if you take your time. Hopefully it will be good. And maybe you'll be able to use the many props, ragdolls, etc into Garry's Mod.
The Orange Box engine is a modified version of the Source Engine. It's still Source but it's modified to support dynamic shadowing and lighting as well as dual core support.

Yeah i liked first person better that Third person cause better aiming and experince
