Can't comment about Redline from personal experience, but reviews have been pretty bad. XAR was maturing by version 1.032 into a pretty damn good racing & flight sim (ignoring some of the sound issues). It's a shame it has been sold to a company that appears much less interest in developing its potential. Also a shame that a dedicated support forum for the original version has been lost. 1.032 is already a gas to fly, so we'll just have to be content with what we've got while we mourn the opportunities missed, I guess.
