			<title>Installing Games on Ubuntu</title>
			<para>Gaming on Linux has been a point of discussion for a long time.
			There is a strong argument that developing the gaming culture on Linux could contribute to its
			commercialisation. An accepted fact is that it is a challenge for the
			programmers to create competitive, open source games that match the sophistication
			that proprietary games provide. However, constant support from the developers,
			users and the community at large have made it possible to develop open source
			games that can give some proprietary games a run for their money.</para>
			<para>The default installation package of Ubuntu 7.10 comes with 17 Ubuntu
			games, including Aisleriot, Solitaire, Gnometris and Mines. In addition, you can
			install many games from other repositories. Different repositories store software according to their
			proprietary status and the level of support each software receives from Canonical and the Ubuntu
			community. This was covered in Lesson 1.</para>
			<instructornote><title>Instructor Notes:</title><para><emphasis role="italic">Understanding repositories is 
			important because games are located in various repositories. You may need to recap on 
			Lesson 1. Pre-install the two games covered in the lesson on every computer prior to starting the day or session otherwise
			this will take up too much time during class.</emphasis></para>
