Why i think call of duty is shit.

cod's running off a 15 year old engine.

That's pulling facts out of your arse. The engine was developed for CoD2 and it was released by 2005, and it's being constantly updated with new features, compatibility and graphical improvement (albeit slightly minimal ones). Just like source (2004), and Unreal engine(1998), and the HPL engine. What's your point?

Actually, it's not, the IW engine which has been used since Cod2 was made in 1999, so rounding to the nearest five is 15 years. So, yeah, it isn't. Just because it wasn't used until 2005 doesn't mean it wasn't around before then.
And the fact is, look at the screenshot from Cod MW1, and MW3/2. Look at the buildings etc, they look the exact same as they did in MW1, they just updated the models. So the point is, the engine is vastly under developed, and HPL is nowhere near as old, and Source, is constantly developed by Valve to become better, (ahem, Half Life 2 - Portal 2) as with the unreal engine. Activision only really update models - I can get comparison pictures if you want.

You're referring to the ID tech engine which is the engine that IWE spawned from. It's not the same engine. At it's core yes, but so are many other engines out there. The difference between the two engines are too vast to make a direct comparison. It's kinda like comparing GSRC with Source (which is a spawn from the GSRC engine, which in turn spawned from the Quake engine), at it's core it's the same engine, but the make-over that the engine has gone over has made it into the independent engine that it is today.
