Stairways Software Releases Greebles -- In a departure from their focus on Mac Internet tools like Anarchie, NetPresenz, and Internet Config, Peter Lewis's Stairways Software has released their first game, called Greebles. Stemming from the two-dimensional maze and block-pushing genre of the arcade game Pengo, Greebles ups the ante with over a dozen types of blocks, numerous types of Greebles (the bad guys), both friendly and nasty computer players, and 100 built-in levels. As you'd expect from Peter Lewis, although you can play Greebles alone, it's also a multi-player game with up to four people playing on a single computer and up to nine computers connected over the Internet (unfortunately 33.6 Kbps modem connections don't provide sufficiently high throughput or sufficiently low latency - see Stuart Cheshire's Bandwidth and Latency articles in TidBITS-367 and TidBITS-368). A Greebles Tracker Web page displays public Greebles games so you can join network games in progress. Greebles requires a 68040 or PowerPC-based Mac; System 7.0 or later; 3 MB of RAM; and a 640 by 480, 256 color-capable system. Network play requires Open Transport 1.1 or later and a TCP/IP network. Greebles is $15 shareware with multiple copy discounts available, and registered users can build their own levels.
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
