I am planning to start a hardcore flight simulator (3 men project). Our target is something close to LockOn. At first we were planning to write an engine from scratch (or using Ogre) until we heard for software such as Unity, Shiva, NeoAxis etc. Right now I am learning Unity (this one is the quickest for me to learn and is good enough in terms of graphics and easy of use).
Now, the questions.
Is Unity powerfull enough to handle such an task? Is it's script enough to wright some advance physics? Or would someone recommend another engine which is more suitable for the task.
