I keep waiting for someone to come along and tell us how sane some other engine is.
What with all the code, and syntax, and third party dependencies.
Or maybe these minor annoyances melt away with the nightmares of integrating third party api's, slow development, and undocumented examples.
I understand how bad performance can be aggravating, but the truth is, if it's slow you may be expecting too much, and just like the deal with sound needing a touch, needs to be worked with.
