I’ve always found Aspyr’s Game Agent an interesting piece of software. It looks at your hardware and lets you know what game are compatible and will run well on it. It simplifies the process, particularly for users that don’t really know what they have running under the hood.
Once you looked for game that first time and you’ve bought what you wanted, is there a motivation to leave Game Agent on your disk? I personally couldn’t see one. It was a one off.
The latest version of the hardware evaluator adds a software update component. This justified a spot in my Applications folder by itself. Like Apple’s own mechanism, updates are checked for manually and can be ignored if desired.
I'm a little upset with Aspyr - just bought NeverwinterNights2 and my new macbook with 4gb of ram can't run it because the videocard isn't compatible. They won't do anything about it so I have useless software now.
