And King's Quest, and Space Quest... and whole host of others. If you head to this nifty website with your iPad web browser, you can gain access to a whole set of old-school Sierra point and click adventures, tailored for the iPad touch interface.
And it's all thanks to Martin Kool, who started off by porting Space Quest across to iPad as a demo, before fixing up th entire game, then a host of others. If you, like me sometimes feel a hankering for some nostalgic adventurin', this is a great solution. The one drawback, of course, is that you have to online to play it - which may make mobile play on the train, for example, next to impossible - but it's still an awesome way to waste an hour or two if you're stuck at home with a mobile device.
