An interesting blog to make the point about engines....

Never underestimate Reality Engine.

It\'s not only that Reality Engine is \"so damn good\".

It\'s because Unreal Engine 3.0 is very limited, it\'s limited in polycounts (yeah they can be ridiculously high), the real-time radiosity pipeline is very small (thus no subsurface scattering and stuff), the mapsize is limited, it lacks day and night shifting so you can\'t make games like FarCry out of it...

Never wondered why wonderman Stieglitz was bought over by Epic??
They made so much offers to the guy just to get him working on UE3.0 and even UE4.0 which they are hopelessly are telling everyone only one man is working on it while they are working on it day and night.

It\'s all one pile of bullcrap... Nothing more.

I\'d prefer Reality Engine anyday, even if it\'s only because of the much lower price.

EDIT: GameBryo 2.0 is the engine of Oblivion, it\'s predecessor was NetImmerse engine which powered games like Neverwinter Nights and Morrowind.
It\'s very versatile but lacks the graphics, IMO gameplay is much better than graphics.
But the best is to have both at top-notch scale.

CryEngine is atm. a very good beginner.
Source too, but it just missed the physics breakthrough and SM3.0...
It could be better though.
