I somehow managed to miss the release of The Ur-Quan Masters alpha 0.4. Just so you understand, alpha 0.3 was quite stable and I was able to complete a game successfully. Alpha 0.4 is even more stable and adds some more features (PC intro/ending sequences, "triscan" filter to name two). It is the best free PC game you will ever play.

Also, the Precursors' remix project contains some pretty kick-ass remixes and covers of the various SC2 tunes. I've made an addon for Ur-Quan Masters which contains what I perceive as the best version for each tune; I'll post a link when I can find some web-space for that (the package currently weighs in at about 90mb) - alternatively I'll do some reading about the new trackerless BitTorrent and see if I can use it instead.

One thing I do wish UQM had is the ability to select a tune at random from a selection (for example, there are two or three very good versions of the Thraddash theme I would like to be able to put in the remix pack). I'll see if I can file a feature requests or maybe even add it to the source code myself.
