Just as a quick follow-up to last weeks post about ET:Xreal:
Version 0.3.0 got released today!
As you can see, it is still a long way to go to replace all the non-free assets, and graphics sure don't look quite as great as all the features of that engine would make you believe (which proves again: it is the artists making a game look good :p ), but it's a start and you can begin brushing up your ET skills again ;)
