But - and this is the big BUT:
No engine is the holy grail!

Here are my thoughts about Unity so far:

-Very powerful
-Used by a lot of companies
-Solid track record
-Damn cheap for its power
-Manual is cluttered and not consistent
-C# is more powerful compared to Unityscript (Javasript) but most examples are written in Unityscript.
-No simple step by step Tutorial for Unityscript and C#
-Lot of overhead for small projects
-Some strange and overcomplicated conventions
-I find it rather unflexible (!)

Compared to other engines I think A8 pro is too high priced atm. It should be something about 600,- usd.
