I've been wanting to enter the game space for some time now. Is this what you do full-time? If so, how did you transition from web dev to game dev?
But I'm mostly using C# and Unity these days. There's too much useful stuff build into Unity to ignore it, and C# is very pleasant so I didn't find it particularly hard to make the jump - there's just a very definite 'Way' Unity wants you to do everything and so most of the time it's just a case of working out what that Way is.
