David Schleinkofer's paintings --gorgeous scenes teeming with futuristic buildings, space crafts, and lasers -- have graced many science fiction magazines and book covers since the 1970s. You'll likely recognize his talents from the packaging artwork for PC games like SimCity 2000, SimCopter, SimTower, and Crossfire.

According to Schleinkofer, he now focuses more on creating landscape paintings, Marine paintings, people and dog portraits, and a Sue Henry mystery book cover now and then.

His Flickr account, though, shows off his work from those bygone sci-fi years -- you can see a couple of his illustrations used as game boxarts below:
