After reading
this article on the dot I decided to give the new KDE-Games for KDE4 a spin. I have to say they've done fantastic work. The SVG graphics look just as good as on the screenshots, and scale beautifully to any resolution. Of course the best graphics technology is useless without actual artwork, so the kudos must also go to the artists. It's all very pretty. Likewise I was impressed by the relative maturity; many of the games seem already perfectly playable and in good shape.
