Working on a few things in cryengine3.
Engine Review on Dec 31st, 2010 - 1 person agrees 2 people don't
Now its beginning to get older, and after using tools for engines of the past 3-2 years, it does begin to show up Source.
It is still a great engine, it works on many set-up's, it does not take much at all to get a map started, and with some basic logic, and the modelling/importing process is not at all difficult, however quite lengthy for today.
Writing out QC's and ensuring it is correct is sometimes a pain. Although basic models are quite easy, whereas certain commands and tasks can be a tricky, and touchy, fixing it can sometimes be something very minor, which can be overlooked when you have a complex QC, especially for characters and vehicles.
Compling maps, in the way Source does, is very old and patience is needed if your not used to it. Models not so bad, but for most engines these days its a one click export, and material files are made on the spot with little manual work aftewrwards. Its purely speed and convenience.
Well documented, everything you need to begin with and learn is in the Valve Docs.
Great games can still be produced and mods, but every year it gets older and even despite the updates valve provide it, other areas are still far behind.
